1. ANTI-BIOTERROR ORGANIZATION "DSO" GEAR DEVELOPMENT PROJECT
THE NEED FOR ANTI-BIOTERROR GEAR The operational actions of DSO agents are mainly investigative and espionage activities. The firearms they're supplied with are high-performance handguns with portability as the main focus, but firearms developed for military and law enforcement organizations aren't designed with special situations like bioterrorism and biological weapons in mind. It's only natural for the DSO to have conceived the idea of developing and supplying "proprietary" gear to prepare agents for the special situations and ops they'll face on a daily basis. REVIVING THE SENTINEL PROJECT A large anti-bioterror force called the "FBC" (Federal Bioterrorism Commission) once existed in the United States of America. The FBC was a military unit tasked with quelling bioterror, an organization with different properties than the DSO, but one that conducted proprietary development of gear utilizing its abundant financial power, equivalent to the military budget of a small country. This anti-bioterror specialized gear development project was codenamed "Sentinel." The Sentinel Project also naturally ceased to exist as a result of the FBC's dissolution. Nevertheless, the revival of this Sentinel Project was arranged by the DSO, which zeroed in on a vast amount of data such as analyses of the various gear and manufactured prototype models devised in this project, as well as the unique circumstances posed by bioterror. 
Leon S. Kennedy & Sentinel Project
Participating as a supervisor to the Sentinel Project revived by the DSO was Leon S. Kennedy, a model agent of the DSO who has experienced scenes of bioterror time and time again. This was due to the fact Leon's extensive experience as a survivor of bioterror incidents was useful for developing gear, such as Raccoon City in 1998, Operation Javier in 2002, and the abduction of the President's daughter in 2004. He once used the powerful "Desert Eagle" magnum handgun and became well-versed in small arms through his many combat experiences, gradually becoming an expert. |

● What Is The DSO?
An American organization formed to defend the nation from many threats, including "bioterrorism."
DSO is an abbreviation of "Division of Security Operations."
Agents with the flexibility and readiness for responding to special circumstances were selected from various organizations to operate within an agent organization under the President's direct command.
In many cases, their ops are centered on espionage and investigations conducted "solo" or with "a small number of people."

● Material Left By The FBC (Excerpt)
There's an interesting passage in the documentation of the FBC's Sentinel Project.
"...OVERALL: As a result of studying and analyzing every conceivable weapon in the world, we, the FBC Small Arms Research Team, have narrowed the handgun base down to three guns, the Beretta corporation's "M92F", the IMI corporation's Desert Eagle and the SIG corporation's "P226R" (omitted) Ultimately, the conclusion we arrived at was that the SIG corporation's P226R was preferable..."
The interesting thing's that, among handguns, it means the FBC Small Arms Research Team narrowed down the M92F, Desert Eagle and P226R.
"The usefulness of the Samurai Edge in combat" is present in another file, proving the "Samurai Edge" used by S.T.A.R.S. was thoroughly analyzed.
※1: SAMURAI EDGE SYSTEM
The Samurai Edge which appears in the games is a M92F-based handgun custom-made by the gunsmith Joe Kendo for the S.T.A.R.S. officers.
In addition to the standard model provided to S.T.A.R.S. officers, Chris, Jill, Barry and Wesker each personally asked Joe Kendo for further customs.

2. SITUATIONAL ANALYSIS, THREE KEYWORDS, & SELECTING THE BASE GUN
WHAT UNIQUE SITUATIONS DOES BIOTERROR CAUSE?
Unlike developing normal gear, developing anti-bioterror gear must account for critical situations such as "confronting creatures mutated by virus-infected organisms and intentionally-made B.O.W. (Bio Organic Weapons)", along with "environments where bioterror has paralyzed lifelines and logistical support."

Unlike developing normal gear, developing anti-bioterror gear must account for critical situations such as "confronting creatures mutated by virus-infected organisms and intentionally-made B.O.W. (Bio Organic Weapons)", along with "environments where bioterror has paralyzed lifelines and logistical support."
|
Some creatures and B.O.W.'s possess tremendous strength and athletic capabilities, are covered with hard skin impervious to bullets, or attack with bodily fluids capable of damaging the human body or materials, and all are extremely aggressive toward humans.
Additionally, combined with the fear of bioterror in areas overawed by chaos, destruction by creatures and B.O.W.'s will also extend the damage to lifeline and traffic functions. Even when acting as members of an anti-bioterror organization, logistical support such as supplying ammunition doesn't always go smoothly. Planned routes to a destination can be blocked, forcing you to search dark and narrow paths devoid of light. Even in situations like that, creatures and B.O.W.'s attack mercilessly. On the basis of such situations, Leon, who became supervisor of the Sentinel Project, presented to the DSO "three keywords" to guide the development of anti-bioterror gear. |
THE KEYS ARE "VERSATILITY, CERTAINTY, & STABILITY"
When developing an anti-bioterror purposed handgun for DSO agents, a base gun was selected first. The keywords for that purpose are the three keywords presented by Leon: "versatility", "certainty", and "stability."
● VERSATILITY
Generally means "wide-ranging usage", but here refers to "ease of replenishing ammo during mission."
Powerful "magnum ammo" is effective against creatures and B.O.W.'s possessing tough outer skin and high durability. This ammo's very difficult to secure in Japan.
As a result, focus was given to handguns that use "9mm Parabellum bullets", which has a high penetration rate and is relatively easy to replenish ammo anywhere. 9mm Parabellum bullets can be found not only in urban gun shops, but also in ordinary households with handguns for self-defense.
● CERTAINTY
"Ensure it works in any situation" is the most important point in developing combat gear. There should never be an accident in the field. Malfunctions such as jamming lead to life-threatening conditions.
Developing handguns usually takes into account changes in weather and the environment.
Dust and sand getting inside, damage and deformation of parts due to extreme high and low temperatures, rust due to rain and seawater, etc. In order to prevent malfunctions caused by these, various ingenuities have been applied to the gun's structure, materials and surface finishing.
However, when taking bioterror into account, this isn't enough.
As Leon himself has experienced, creatures and B.O.W.'s may spew bodily fluids similar to strong acids. Therefore special measures need to be considered particularly for the materials and surface finishing.
● STABILITY
Handguns are much smaller and lighter than assault rifles or submachine guns and enable swift movement while standing, often used to confront targets at short distances.
In close combat it's important to "hit the target quickly and accurately." There are some creatures and B.O.W.'s that attack by closing the distance from a few meters away. In a bioterror field, not taking a shot's simply exposing yourself.
Manipulating a gun's trigger and lever without stress leads to "speed." In addition, Leon argues that ease of aiming and hit accuracy, and especially the sense of stability when holding a gun, are points to "accuracy", and a grip that fits in the hand is indispensable.
A gun that reflects the shooter's ideals is the agent's partner. Leon also states such a great sense of trust in a gun will bring stability to one's mind in situations where they're mentally driven into extreme conditions.

SELECTING THE "P226E2"
As the custom base for an anti-bioterror specialized handgun, from the three keywords of versatility, certainty and stability, Leon selected the P226E2 handgun from SIG, a well-established firearms manufacturer prided by the industrial powerhouse Switzerland. The "P226", elaborate and Swiss-made, once competed with the M92F for final selection by the US military. The M92F has evolved into the S.T.A.R.S. Samurai Edge. How will the P226E2 evolve in the hands of the DSO? Through this, the "Sentinel Project" finally entered the full-scale development phase. |
|
3. WHAT CUSTOMS ARE SPECIALIZED FOR BIOTERROR?
US NAVY SPECIAL OPERATIONS FORCE SEALS & SIG P226 The P226E2, chosen as the base for the DSO's proprietary anti-bioterror handgun, is an improved model of the P226 adopted by the US Navy Special Operations Force "SEALs." SEALs have many "grand" missions such as infiltration, reconnaissance and surveillance and are particularly adept at underwater ops. The "sentinel" in the Sentinel Project advanced by the DSO is one of the vital roles of "sentry." DSO agents head into the field first to advantageously combat bioterror, DSO agents will be first on the scene and, acting as the organization's "eyes", their espionage and investigation lead to incidents being resolved. The P226 was selected as a buddy by the SEALs who, like the DSO, take on the role of sentries. One could say the improved model P226E2 happens to be an ideal model as a base for a purpose-built anti-bioterror handgun. |
● What Are SEALs?
US Navy Special Operations Force "Navy SEALs." SEALs is an acronym of Sea, Air and Land, but as the name suggests, they're an elite unit of small number that conduct missions on the sea, in the air and on land. Their missions are complex and diverse, such as coastal patrols, airborne infiltration and enemy area recon, so their gear's often developed independently or made-to-order by manufacturers. The P226 used by the SEALs was also switched to rust-resistant specifications per their request.

"SIG P226E2" BASIC PERFORMANCE & IMPROVEMENTS
The P226E2 balances "safety" to prevent accidental discharge while carrying along with "rapid response" capable of reacting swiftly to situations without operating the safety. Also, "E2" stands for "Enhanced Ergonomics", and as these words indicate, it adopts a design that incorporates "ergonomics" with favorable operability. Of course, the model's exceptional in terms of accuracy and durability, but if it's to be provided to DSO agents, further improvements were required with "fighting bioterrorism" in mind. By solving the following issues based on the keywords of "versatility, certainty and stability", the DSO would perfect the P226E2 as an anti-bioterror purposed handgun. |
|
Increase Magazine Load
If the 9mm Parabellum bullet's inferior in power compared to the Magnum bullet, it'll be compensated for by the number of bullets. The magazine should be loaded with as much ammo as possible.
[Main Improvements] Magazine
Improve Corrosion Resistance of Exterior Parts
Considering the effects of bodily fluids generated by creatures and B.O.W.'s, it's essential to review the materials and finish processing, especially for moving parts, in order to prevent the parts from deteriorating or malfunctioning.
[Main Improvements] Slide, hammer, trigger, magazine catch, slide stop, decocking lever, takedown lever, etc.
Improve Speed of Operation
Endeavoring to improve the operability of the various levers to prevent any operational mishaps will lead to quicker shooting.
The setting should be based on the notion of single action (※1) fire.
[Main Improvements] Hammer, trigger, magazine catch, slide stop, etc.
Improve Accuracy
There's a need to pursue further stability while wielding the gun, on top of ease of aiming in the dark.
Especially when gripping, think not only of how easy it is to grip but also the difficulty in sliding. Additionally since it's effective to shoot multiple creatures and B.O.W.'s in weak points, recoil must be further reduced so it can be used easily during continuous firing.
[Main Improvements] Grip, muzzle (barrel), front/rear sight, etc.
※1 "Single action" refers to a handgun's firing mechanism, meaning the hammer moves (action) while pulling the trigger. If the hammer's raised prior to pulling the trigger, it'll fire in single action.
If the 9mm Parabellum bullet's inferior in power compared to the Magnum bullet, it'll be compensated for by the number of bullets. The magazine should be loaded with as much ammo as possible.

4. THE ROAD TO FINALIZING SPECS (1) INITIAL DESIGNS
In the fourth to fifth installments of this series, we'll take a break from "Sentinel Nine Inside The BIOHAZARD World" to introduce the planning and development segments of how the specifications for the 2013 limited edition "Sentinel Nine Leon Model" were decided.
In the third article of this series, we decided on the (D) plan for the style direction. After this, the specs for each part will be finalized, but let's start by looking at the features of (D) before the changes.
● MAIN SPECS OF PROPOSAL (D)
A "flash hider" is attached to the muzzle (barrel tip). The flash hider's a part that suppresses muzzle flash (flame) visible from the muzzle when firing, prevents the shooter from being blinded by the glare of the flame while preventing an enemy from knowing their firing position.
In combat, it's a great advantage to "not let the opponent know your position." This is also true in online matches such as FPS.
We also added a tail-shaped guard known as a "beavertail" to the grip. When the trigger's pulled, the vigorously retracting slide moves the hammer by pushing it. This prevents the hammer from striking the base of the thumb on the hand holding the grip.
On the side there's a "thumb rest" for the thumb as well as a DSO medallion. The silhouette at the rear of the grip has been straightened to create a much sharper overall image.
(D-1) shows a sighting diagram with the front and rear sights superimposed. Surrounding the front sight's a rear sight called a "ghost ring," which is designed for close range and quick sighting. The yellow part in the figure's a luminescent material that allows the user to aim in dark places.
This ghost ring sight's not to everyone's liking in terms of usability though. We worked with CAPCOM's Executive Director Takeuchi on the sights until the very last minute.
(D) When we submitted the proposal, CAPCOM requested we use a long magazine.
The standard magazine of the "P226E2" holds 15 rounds, but we'll later adopt a long magazine that holds 20 rounds.
Since handguns have a low ammo capacity (the number of rounds that can fit in a single magazine), if you mess up, you'll run out of ammo at a critical moment and need to change the magazine. Of course, you can't shoot during this time, so many people might've felt frustrated when they ran out of ammo in the face of an approaching creature in a game.
A long magazine reduces the number of magazine changes, and the difference of "plus 5 rounds" is quite significant for handguns, where each shot's used with caution.

(E) is the feedback from CAPCOM. (We resubmitted Proposal (D) with the aforementioned long magazine added to have it checked.)
The writer was Mr. Takeuchi, CAPCOM Executive Director. As expected of a gun enthusiast, he had many "suggestions" only he could make since he's familiar with guns.
If you're not so familiar with guns, you tend to focus on appearances, but Mr. Takeuchi's suggestions also took into account "actual usability" and the roles of each part.
Incidentally, it was around this time that the concept of the Sentinel Nine inside the BIOHAZARD world began to take shape.
Some of CAPCOM's suggestions are linked to the keywords "versatility, reliability, and stability" that appeared in the second issue of this series, as well as to the issues set forth by the DSO in the third part. If you compare the background settings in the second and third articles with the following proposals, you'll understand why we're so particular about this customization.

Improvements |
Suggestions by CAPCOM |
Flash Hider |
We want to keep the shape simple and provide a port (hole) at the top. 【Commentary】Guns use the pressure of gas generated when gunpowder's ignited to send bullets flying. If there's a port, gas will be ejected from the port, minimizing muzzle jump. |
Body Color |
Is it possible to change the overall color? (e.g. matte black, bluish black, etc.) 【Commentary】Many black guns are used in ops, but "matte black" in the proposal refers a rough non-shine surface, while "bluish black" refers to a gun with a rust inhibitor (bluing agent) applied. |
Hammer |
In order to create a unified design, we'd like to match the shape of the punchings to the hammer. 【Commentary】When the hammer's lightened by making holes (punching), it moves faster when the trigger's pulled, shortening the time lag before a bullet's fired. |
Trigger |
The shape should be suitable for single action firing. 【Commentary】The P226E2 can be fired in either single action or double action (※1). The trigger's heavier and the trigger pull distance is longer for double action firing, so single action firing is more suitable for rapid response during ops. |
Grip |
We want a higher grip. The grip's silhouette is OK. 【Commentary】The closer the hand holding the grip is to the height of the barrel, the less likely the muzzle will jump when firing. |
Front/Rear Sight |
Ghost ring sights are hard to see, so why not cut off the top half of the rings? 【Commentary】The ease of aiming the sight may also affect the usability of the gun itself. The design must take into consideration the ease of seeing the dot (marker), the field of view through the sight, and the ease of aligning the sight with the front sight. |
Long Magazine |
We want to make it a "SEALs Magazine." 【Commentary】The long magazines for the P226 used by SEALs are commonly known as "SEALs magazines." (The magazine in (E) is a standard P226 magazine extended to 20 rounds, and the design around the bottom of the magazine's different from the SEALs magazine.) |
※1・"Single action" & "double action" refer to a handgun's firing mechanism. If the hammer's raised before the trigger's pulled, the gun fires in single action. If the trigger's pulled without the hammer raised, the gun fires in double action.
● CREATING THE PROTOTYPES
While considering whether the feedback from (E) was feasible as a product, Tokyo Marui finally start to build a prototype to verify the design.
The prototype actually created is shown in (F) below. Since there are no molds for newly made parts, the staff in charge of the trigger and flash hider, for which designs haven't yet been decided, make them bit-by-bit by hand.
Even though they're handmade, the finished products are true craftsmanship. It's such a waste that we can only show them to you in pictures.
Until a prototype's made, it's a purely theoretical design. We can't confirm whether a gun's really easy to use or not until we actually make a prototype then use it. Also, there's often a difference in impressions for a gun when it's seen in 2D and when it's seen in 3D.
After making these minor corrections, we asked CAPCOM to check the completed prototype.
The prototype (F) is getting pretty close to the final specs, but the trial and error process continues. For more details, please refer to "THE ROAD TO FINALIZING SPECS (2) LATE STAGE DESIGN"!

6. CUSTOM ANALYSIS (1) ADAPTABILITY TO SPECIAL ENVIRONMENTS
BIRTH OF THE SENTINEL NINE Within the DSO's Sentinel Project, various custom-made handguns purpose-built for combatting bioterrorism were developed, based upon the P226E2. Two types of custom candidates were narrowed down in the final stage, then after passing through a trial (※1), the Sentinel Nine won and was adopted by the DSO. The model name Sentinel Nine was originally a codename attached during development representing the "9th prototype", but the ammunition it uses is sometimes the 9mm Parabellum bullet, so it would simply be used as the name after being formally adopted by the DSO. The Sentinel Nine was reborn from the P226E2 at the hands of the DSO as an anti-bioterror dedicated handgun. First let's look at the final specifications from "adaptability to special environments." ※1. When a new firearm's adopted by the military or police an employment test is conducted, referred to as a "trial." Within the trial, tens of thousands of shots are fired to test accuracy and durability, and rigorous tests against drops, impacts, high and low temperatures etc. are performed, with improvements and tests repeated until it attains a standard for adoption. If it's a DSO trial with an anti-bioterror focus, the contents will be even more severe. |
|
|
THE FIELDS OF "DARKNESS" AGENTS FACE
The most difficult situation to avoid in bioterror fields is "darkness." It's always night out once a day and even during the daytime many indoor areas are poorly lit. Situations where the power supply's cut and there may be no lighting are also conceivable. If the enemies being confronted are humans like the agents, darkness is a 50/50 situation. However, some creatures and B.O.W.'s can detect prey via sound or smell. Fighting in the dark can be an overwhelming disadvantage for agent personnel. The Sentinel Nine assumes the following measures for use in the dark. |
|
|
● Front Sight & Rear Sight
The Sentinel Nine's sights are focused on acquiring a target. The dot parts of the sights are filled with a "phosphorescent agent" that stores and emits light, making them visible even in the dark. The dots on the front sight are square and the dots on the rear are shaped a very rare triangular, but this is designed to ensure you can reliably see and act quickly against unexpected attacks. The sights have a "stealth shape" where reflected light's less likely to affect sighting, with the sights having been made smaller and less likely to catch on clothing. ● Body Color Taking ops in the dark into consideration, it's usually desirable to unify the color of gear with a less noticeable black. However, it could fall as a result of bad footing. It can be knocked away by a creature's powerful blow. In the unlikely event you lose that gun, finding a black-colored gun in the dark would prove difficult. The Sentinel Nine dares to make some parts, such as the slide, silver in order to "make it easier to see the gun even in dim darkness." ● Mount Rail The mount rail's a specification of the base P226E2 and not a Sentinel Nine customization, but it's an indispensable spec for ops in the dark. The grooves under the gun in front of the trigger are what's called the mount rail and most guns use a 20mm wide (Picatinny standard) mount rail. This part can be equipped with flashlights or laser pointers of the same standard. Since it's possible to switch on and illuminate a light etc while grasping the gun in both hands, mount rail models are increasingly being adopted especially in units that engage in a great deal of indoor and night combat. |
THOROUGH ANTI-"CORROSION" MEASURES
The Sentinel Nine has been subjected to a phosphate film treatment (parkerizing). This is a major surface treatment for preventing rust that can cause malfunctions, which is also utilized on the P226 of the US Navy Special Operations Force SEALs, who are very active in water. However there's something else to watch out for in the field of bioterror besides rust caused by rain or moisture. That's bodily fluids from creatures or B.O.W.'s. These bodily fluids not only harm the human body but may also corrode materials and deterioate them. For that reason, the Sentinel Nine adds a special surface treatment, unaffected by bodily fluids, onto the phosphate film treatment. From the precaution that these treatments are applied not only to the external parts but also the internals, it's possible to grasp the magnitude of the effect of "corrosion." The slide that's key to its operation is made through cutting using a special alloy material resistant to rust, special chemicals, etc, taking its strength and durability into account. On the slide's left side is the model name (SENTINEL NINE), caliber (9mmX19), organization name (Division of Security Operations), and engraved with the DSO's motto "PEACE THROUGH FIGHTING."

7. CUSTOM ANALYSIS (2) MUZZLE CONTROL & OPERABILITY
FIGHTING BIOTERROR WITH THE 9MM PARABELLUM
The 9mm Parabellum bullet used in the Sentinel Nine is among the "most readily available ammunition" popular around the world.
Although within a single shot it's inferior in power to the Magnum bullets used by the Desert Eagle, the 9mm Parabellum bullet has the advantage of supplementation. That is, "recoil's minor" and because the size (diameter) of the bullet's small, "the magazine number's large." If recoil's minor, it's easy to control the muzzle direction even if firing in quick succession, so you can aim for a hit after the second shot.
If you can fire multiple bullets at the weak point of a creature or B.O.W., even the 9mm Parabellum can expect significant damage. If you have a DSO agent's skills and the Sentinel Nine's performance, you can expect a bigger effect than a Magnum bullet.
▲ 9mm Parabellum Bullet
The name "Parabellum" is derived from the Latin phrase "Desire peace, prepare for war" and it's connected to the DSO motto "Peace Through Fighting."

ACCURATE FIRE ON WEAK POINTS & CONTROLLING RECOIL
A gun's bullets don't hit as intended if aim's inaccurate. In the action of "pulling the trigger to fire the bullet", there are many elements that cause a decrease in hit rate, such as shaking when using the trigger, significant recoil when firing, and muzzle flash.
In order to strike several bullets at the weak points of creatures and B.O.W.'s, the Sentinel Nine compensates for aspects the shooter's skills alone can't cover.

● Flash Hider & Long Barrel
The Sentinel Nine's barrel is about 10mm longer than that of the P226E2. By extending the barrel length, the bullets it fires have a more stable trajectory, and the tip's threaded to allow silencers to be easily installed. (※1) A "flash hider" for suppressing muzzle flash is standard on this thread. The front face-like spike shape's designed to limit the spread of the muzzle flash. In addition, the side port (hole) is for releasing the gas to be ejected and has the effect of suppressing muzzle jump in reaction to the ejected gas. ● Hybrid Grip Although the power of the 9mm Parabellum bullet's inferior to the Magnum bullet, the bullets it fires have sufficient offensive power and recoil when firing them is minor enough to be easily restrained by human strength. The Sentinel Nine seeks ease of grip and fit to hold the recoiling gun firmly with both hands. As a result of thorough research on the differences in roundness and angle, we arrived at this "hybrid grip." A grip loaded with much pickiness such as a thumb rest intended for right-hand use, a DSO medallion on just one side, and a rubber finish making sliding harder, providing perfect holdability. ● B Trigger The Sentinel Nine trigger's called a "B Trigger" as it resembles the letter "B." Handgun trigger shapes vary but the B Trigger's a particularly unique design. The Sentinel Nine's for single action use capable of responding immediately even in emergencies, and the trigger in single action's at position (B). The reason why the front of the trigger (the part touching the finger) is flat is to transmit the force of the finger to the trigger without waste when pulling the trigger from position (B). The more force applied to the finger pulling the trigger, the easier the muzzle will shake. Smooth triggering is an important factor in precision shooting. In addition, the B Trigger has two punched holes. When the trigger returns to position (B) after firing, the trigger's lightened so returns faster. It's a slight difference that goes unnoticed initially, but the nerves in the fingertips are sensitive to differences in how quickly the trigger returns. Especially when pulling the trigger many times and firing rapidly (sequential firing without pause), if the trigger feels uncomfortable it'll cause the shooter significant stress. |
INCREASING BULLET NUMBER & SMOOTH MAGAZINE CATCHING
When using 9mm Parabellum bullets, the DSO enables rapid-fire attacks against creatures and B.O.W.'s which means more bullets are spent.
If the magazine placed in the gun's empty, you'll be unprotected while changing the magazine. However, if the number of bullets in the magazine's increased as much as possible, the number of magazine changes is reduced, and if the magazine can be replaced quickly and smoothly, the gap will be smaller.
● Long Magazine
The long magazine used in the Sentinel Nine holds 20 rounds. This is five more than the usual magazine for the P226E2, so the magazine's also longer.
This magazine, also referred to as a "SEALs magazine", is heavy because the bottom's reinforced with an iron plate. If you press the magazine catch it'll easily fall by its own weight allowing for the magazine to be efficiently swapped out.
● Magazine Catch
A large square-type magazine catch is used to ensure the magazine can be replaced in any situation. Although it's large and easy to push, it's designed so that it won't jam while handling the Sentinel Nine.

The DSO resurrected the Sentinel Project previously advanced by the FBC and finally invented the Sentinel Nine, a proprietary handgun for facing bioterrorism.
At the DSO only a few were initially manufactured and combat data was collected by Leon, the Sentinel Project's supervisor.
However in 2013, before Leon received the Sentinel Nine, a large-scale bioterror incident occurred at Tall Oaks in the United States.
Although it was finally in Leon's hands after the incident was resolved, combat data collection has yet to be completed. Full-fledged production of the Sentinel Nine and the official issuing date to DSO agents remain undecided.
● Gun Case
The gun case containing the Sentinel Nine is also supplied by the DSO. Made of a high-strength polymer with excellent shock absorption, it's a tough case that doesn't affect the gun stored inside, even if it were dropped from the sky or run over by a tank.
Displayed on top of the case are the DSO emblem, model name, serial number, etc., which prove the product's supplied by the DSO.

-INTERVIEW WITH TOKYO MARUI PR-
"SENTINEL NINE" DEVELOPMENT KICKS OFF
CAPCOM Managing Executive Officer Takeuchi-san's quite a gun-nut and we meet every time at the Osaka Shot Show (a military event). Whenever we meet up, our favorite phrase is "we want to do some new collaboration project."
It was when we met in 2011 that we were able to develop the Sentinel Nine. That year was exciting with BIOHAZARD's 15th anniversary and we expected further excitement in 2012 with the release of the movie "biohazard DAMNATION", so we said "let's get started with the collaboration model project" in earnest.
Of course at that time, the concept of the Sentinel Nine hadn't been made yet. However we resold the Chris and Barry models of the Samurai Edge in 2011 and were about to begin a new development with the Samurai Edge.
The main character of "BIOHAZARD 6" was Leon, so we decided on the "Leon Model" early on.
We also wanted to use the familiar Desert Eagle as the base. If you've purchased the "Desert Eagle 50AE 10-inch Barrel Leon Custom", you'll find the "Desert Eagle 10-inch Full Barrel Custom" in the manual as "Leon's personal rough sketch." We thought this would make a good product.

● Desert Eagle 10-inch Full Barrel Custom
Leon's rough sketch published in the manual of the Leon Custom released as a limited edition in 2008.
But Leon's Desert Eagle has been released in three types and within Tokyo Marui there were voices asking "Is the Desert Eagle really all that good?", so we considered other models as well.
Then we received a request from the CAPCOM producers to "make it a model that's not the Desert Eagle", so we decided on the direction of "a new model, organized like the Samurai Edge, different from the Desert Eagle." (※1)
HANDGUNS THAT AROSE AS CANDIDATES FOR THE CUSTOM BASE
The direction of "a new model, organized like the Samurai Edge, different from the Desert Eagle", had been decided, and next was squeezing out the handgun that'd be the base.
Tokyo Marui's constantly considering custom models for various handguns. Firstly we chose two proposals based on the "Glock" and "SIG P226" then asked for CAPCOM's opinion.
There aren't actually that many handguns usable as custom bases.
In addition to the Glock and SIG P226, there's the M92F, M1911, Desert Eagle, high capacity models (our Hi-CAPA 5.1 and such), which are popular around the world and have an abundance of custom parts.
However, the M92F is the base gun for the Samurai Edge, while the Desert Eagle was excluded from these candidates.
We've already developed various variations of the M1911 and Hi-CAPA so they'd have little impact as valuable collab models.
There are other models such as the "XDM-40", "PX4" or "FN5-7", but these are relatively new models so questions arose relating to their popularity compared to major models like the M92F and M1911.
It seems CAPCOM wanted a "SIG P226 Custom" so we received the OK since we based it on the P226E2, an improved model of the P226.
The "SIG P226" gun's an exceptionally "perfect tool" and an ideal model for handpicked DSO agents. Taking advantage of its strengths, we'll apply a BIOHAZARD-like custom that takes "anti-bioterror" into account.
● SIG SAUER P226R
A high-performance automatic pistol used by military and police organizations in various countries, including the US Navy Special Operations Force SEALs. The P226E2 is an improved model of the P226R.
