See the discussion page for fictional weapons.

The following weapons are used in the game Metal Gear Solid: Peace Walker:



Mk. 22 Mod 0 "Hush Puppy" (Smith & Wesson Model 39)

A Mk. 22 Mod 0 (Navy modified Smith & Wesson Model 39) modified into a tranquillizer gun. A suppressor has been fitted and further upgrades in the game increases its durability before it wears out.

Mk22 Mod 0 (Navy modified Smith & Wesson 39) - 9x19mm. Note slide locking mechanism to reduce noise, tall iron sights, and threaded barrel.
Note the taller sights allowing them to be used together with a suppressor. You'll only be able to use the Mk. 22 without the suppressor once that wears out and has to be removed.

Colt M1911A1

A normal M1911A1 is found as well as the custom M1911A1 Big Boss uses in Metal Gear Solid 3: Snake Eater. A suppressor can be fitted from Rank 2 and 4 onwards for the normal and custom version respectively, further upgrades in the game increases its durability before it wears out.

M1911A1 - .45 ACP
This upgrade looks interesting. Note the new hammer, extended slide release and safety levers, grip, the addition of cocking serrations at the front of the slide, a different suppressor, longer trigger, new sights and differently shaped beavertail.
MGS4 image of the M1911 Custom for comparison. Some details are simplified on the Peace Walker version, but it is clearly supposed to be the same gun.

Makarov PM

A Makarov PM serves as the most inconspicuous handgun carrying a S rank, increasing camouflage rating compared to other firearms. Zadornov carries one during the comic cutscenes.

Makarov PM - 9x18mm Makarov

6P9 PB

The 6P9 PB is a modified Makarov PM that contains an integral suppressor that never wears out during gameplay.

6P9 PB - 9x19mm Makarov

Mauser M712 Schnellfeuer

The Mauser M712 Schnellfeuer with a 10-round magazine is available in the game, though it's simply called "C96".

Mauser M712 Schnellfeuer - 7.63x25mm Mauser
Note fire-selector and flush magazine well.

Smith & Wesson Model 19

The Smith & Wesson Model 19 gains a longer barrel at Rank 3 reducing recoil and Rank 4 introduces a laser sight.

Smith & Wesson Model 19 - .357 Magnum


The Leuchtpistole is in the game. Further upgrades introduce a stock to mitigate recoil. This turns the Leuchtpistole into a Sturmpistole.

Leuchtpistole - 26.65mm


The Sturmpistole is a WWII German flare pistol, modified to shoot grenades in lieu of standard flares.


EZ Gun (modified FP-45 Liberator)

The modified FP-45 Liberator appears as the "EZ Gun", which fires special rounds that either recover LIFE or PSYCHE, most beneficial during CO-OP gameplay, and the "Strike Marker", which functions just like its em-placed and thrown counterparts (except that you use the gun to launch the marker, of course). The pistol is equipped with a built-in suppressor that never wears off. The PSYCHE version, for some reason, required Big Boss to get Paz to fall asleep during a hangout at the beach and pat her down to get the blueprints for development, despite being able to simply deliver it to him while on-base and on-duty.

Besides the LIFE or PSYCHE variants, there were also Support beacon guns that shared a similar design to the EZ gun, although unlike the prior two, the two weren't explicitly identified as such in-game.

The FP-45 Liberator Pistol - .45 ACP. The EZ gun is based on the Liberator Pistol

Submachine Guns

Ingram MAC-10

The MAC-10 is available in two forms without an extended barrel with can be equipped with a suppressor and one with an extended barrel including shroud for increased accuracy.

Ingram MAC-10 - .45 ACP

M1928/A1 Thompson

The Thompson makes an appearance in it's M1928A1 variant, though it can be upgraded to the original M1928 variant with a vertical foregrip for increased stability and a 50 round drum magazine. The "Tommy Gun's" inclusion could be a throwback to The Pain's own M1928 in Metal Gear Solid 3: Snake Eater

Thompson M1928 - .45 ACP
Rank 3 M1928A1 Thompson. The 50-round drum is a Rank 3 upgrade, while the foregrip was added at Rank 2.

Heckler & Koch MP5A2

An early MP5A2 variant with a "slimline" handgun and a straight box magazine is present in the game and can be attached with a suppressor.

Heckler & Koch MP5A2 - 9x19mm Parabellum

Heckler & Koch MP5SD2

The integrally suppressed version of the MP5A2 is also available. Unlike its detachable counterpart, this suppressor does not wear out.

Heckler & Koch MP5SD2 - 9x19mm Parabellum

Česká Zbrojovka SA Vz. 61 "Skorpion"

The ČZ SA Vz.61 "Škorpion" appears as "Uz61" in the game. Holds only 20 rounds, but can be used in conjunction with the shield.

Skorpion SA Vz. 61 with 20 round magazine - .320 ACP

Assault/Battle Rifles

Colt M16A1

The M16A1 is Big Boss' preferred weapon during cutscenes and can be fitted with a suppressor, grenade launcher, shotgun and/or laser sight.

M16A1 - 5.56x45mm NATO

Colt Model 653

The Model 653 can be fitted with a suppressor, grenade launcher or shotgun.

Colt Model 653 - 5.56x45mm NATO


A highly modified AR-15 platform used by The Boss in Metal Gear Solid 3: Snake Eater. Carries an "infinity shaped" drum magazine granting infinite ammo. For unknown reasons, you have to knock Kazuhira Miller unconscious during a get-together at a beach and pat him down to get the blueprints to develop it, despite being capable of delivering it to Big Boss in person without it.


Izhmash AK-47

The AK-47 is called an "RK-47" and can be fitted with a GP-25 grenade launcher. For some reason, the reloading animation uses the charging handle animation of AR-15 rifles, despite other AK rifles using a correct animation.

AK-47 - 7.62x39mm
Note that this is a screen capture from one of the demonstrations. In the full game, these Peace Sentinel troopers use the M653.
Note the straight AKM stock

The Hungarian AMD-63 appears as "AMD63" in the game, although it is implied to actually be the Romanian version, the Pistolia Militarea Model 1963.

Fegyver és Gépgyár (FÉG) AMD-63 - 7.63x39mm


A Hungarian AMD-65 is called an "ADM65" in game and is a AK-type carbine with folding wire stock and vertical foregrip. Just like the Thompson, this weapon is a Throwback from MGS3, sometimes seen carried by a few members of the Ocelot Unit.

Fegyver és Gépgyár (FÉG) AMD-65 - 7.62x39mm

Steyr AUG A1

The AUG A1 is called the "SUG" in game, its reception in MSF is well liked and becomes the service rifle of Outer Heaven in the Metal Gear universe. This weapon is anachronistic, because it was not developed until 1977 and the game takes place in '74.

Steyr AUG - 5.56x45mm NATO

Heckler & Koch G11

The G11 is noted in game for its high accuracy and rate of fire. The prototype variant depicted in game is the second prototype of the G11 developed around 1975. Although technically anachronistic due to the date, the small amount of time between the events of the game and the real life date render this inconsequential.

Heckler & Koch G11 Prototype 2 - 4.3mm

FN FAL Paratrooper

The Fabrique Nationale FAL Paratrooper can be upgraded to have a shorter barrel for easier handling and equipped with a laser sight at Rank 4.

FN FAL Paratrooper - 7.62x51mm NATO


Ithaca 37

The Ithaca 37 makes an appearance with a sawed-off stock and barrel. further upgrades fit the gun with an extended magazine tube, a suppressor, a rifle scope, full-length barrel, and a full stock. It is also the under-barrel shotgun attachment for the Colt M16A1 and Model 653.

Ithaca 37 - 12 Gauge

Heckler & Koch CAWS

The Heckler & Koch CAWS shotgun's in-game description says that this it is a "Prototype full-auto shotgun. Its outstanding capacity and firing speed make it the most powerful shotgun in the world". It is anachronistic, because it was developed in the 1980s.

Heckler & Koch CAWS - 12 Gauge

"Twin Barrel"

The "Twin Barrel" is a 12 Gauge Double Barreled Shotgun. It initially starts off as a regular length 12 Gauge Double Barreled Shotgun. Rank 2 saws the barrel and stock off. The other ranks reduce the reload time of the gun, weight and kickback. It also had two types of ammunition. The usual lethal slugs, and rubber slugs that only knock the enemy out.

Remington Spartan Sawed Off shotgun - 12 gauge
"Twin Barrel" from Rank 2 and on.

Franchi SPAS-12

The Franchi SPAS-12 is another usable shotgun in the game. Appears in semi-automatic mode. Another anachronistic weapon in the game, as it was not developed until 1979.

Franchi SPAS-12 - 12 Gauge

Sniper/Anti-Tank Rifles

SVD Dragunov

The Soviet Union's official sniper rifle at the time of the game. It is the exact same as in Metal Gear Solid: Portable Ops and MGS3 in terms of design and use, at early levels at least. In mid levels, the SVD Dragunov obtains an extended magazine, granting 10 extra rounds. At its full development, it gets equipped with an anachronistic 1980s NSPUM (1PN58) night vision scope; it does not appear to be the earlier NSPU (1PN34) since there is a circle (representing a switch) at the top of the scope mounting; on an NSPU it would be at the bottom.

SVD Dragunov sniper rifle - 7.62x54mm R

Mosin Nagant

Mosin Nagant sniper rifle modified to fire tranquilizer darts. The same gun as used by "The End" in Metal Gear Solid 3: Snake Eater.

Full-length, Mosin Nagant M91/30 Sniper Rifle with Russian PU 3.5x sniper scope and down turned bolt handle - 7.62x54mm R
Mosin Nagant tranquilizer rifle upgraded to Rank 3. Fitted with the same pistol grip and skeleton stock found on "The End's" Mosin Nagant.

Walther WA 2000

Another usable sniper in the game is the WA 2000 The in-game description says that it's hard to handle but very accurate. Can penetrate armor with a single shot. Anachronistic as it was not developed until 1982.

Walther WA 2000 - .300 Win Mag


In the gameplay trailer it's equipped with a suppressor and has a large (20 rounds) magazine. It can penetrate the helmet of a soldier with one shot; also, a shot in the arm from this gun seems to be deadly.

M21 Sniper Rifle - 7.62x51mm NATO


The M1-C is another usable sniper rifle in the game.

M1-C Sniper Variant with M82 scope - .30-06.

Remington 700

The Remington 700 appears as M700 in the game.

Remington 700 BDL rifle with no iron sights and scope (current production) - .308 Winchester

Degtyarov PTRD-41

The PTRD-41 is a powerful weapon but holds only one round.

PTRD-41 anti-tank rifle - 14.5x114mm

Degtyarov PTRS-41

The PTRS-41 rifle appears as "PTRS1941" and fires in semi-auto. Has a 5-round magazine capacity.

PTRS-41 anti-tank rifle - 14.5x114mm

Machine Guns


The PKM is available in hand-held or vehicle-mounted varieties. Upgrades shorten the barrel, increase damage and fitted with larger magazine box.

PKM with latest version of the flash hider - 7.62x54mm R


The RPK is used mainly be Soviet soldiers in the game.

RPK light machine gun with 75-round drum magazine - 7.62x39mm


The M60 is a devastating weapon but also significantly reduces the player's mobility. It produces higher recoil than many other small arms and has a very low rate of fire. Can be upgraded to reduce its length which also reduces weight.

M60 machine gun with bipod folded - 7.62x51mm NATO


Snake (without any clothes on the upper body apart from 2 bullet belts) is seen firing the DShKm in a screenshot. In the final game itself, it was frequently used by the Peace Sentinels at strategically important locations, such as Catarata de la Muerta and Fuerte la Ladera.

The MG3 is a very powerful machine gun and an excellent choice against heavy targets such as armored vehicles, tanks and helicopters.

MG3 Machine Gun - 7.62x51mm NATO

Stoner 63

Stoner 63 in light machine gun configuration appears in-game called "M63A1". Further upgrades fit the gun with shortened barrel, larger magazine box and armor piercing rounds.

Stoner 63 - 5.56x45mm

GE M134 Minigun

This man-portable Minigun has a very good fire-power and an amazing rate of fire however it slows down the player heavily. And like everybody should know, a man-portable Minigun is very unrealistic.

General Electric M134 - 7.62x51mm



The M203 can be attached to the M16A1 or Model 653 and fires either high explosive or smoke grenades.

M16A1 with M203 - 40x46mm


Can be mounted on the AK-47. Anachronistic, as it was not introduced until 1978.

GP-25 grenade launcher - 40mm

The RPG-2 (the predecessor of the RPG-7) is one of the usable launchers in the game. It weighs around 300 grams more than the M72 LAW, but Big Boss can carry one extra rocket for it.

RPG-2 with PG-2 rocket - 40mm


The RPG-7 also makes an appearance in the game. It is obtained by the player and used by the enemies near the end of the game.It is one of the launchers of the game that can be unlocked. It also has a PGO-7 scope attached to it for accurate aimming.Like in most MGS games it is always used by Snake.

RPG-7 with PGO-7 scope and PG-7VM rocket 40mm


Single-shot disposable anti-tank rocket launcher. You'll occasionally use this in cutscenes, where you'll get a good representation of the launcher's flip-up sights. With each upgrade, the LAW will get a firepower boost, along with a different color scheme, except for the last and final upgrade where it becomes longer, still retaining the black paint job. Unlike most procurable weapons in the game, it does not require that the player get design specs to develop it. A M72 LAW was also taken by several FSLN soldiers in the ending cutscene for the find the FSLN Comandante mission early in Chapter 1, with Big Boss later using it to take out Kidnapper drones, as well as attempting to take out the Chrysalis weapon before learning of its improbably quick evasive maneuvers.

M72 LAW - 66mm

FIM-43 Redeye

The FIM-43 Redeye appears in the game as a guided missile launcher. Being an early version of it, its lock-on computer is weaker and takes a considerable time to lock-on targets. Can be dumb-fired or fired after locking on. Lock-on works on both air and ground targets, despite the real weapon only being capable of engaging airborne targets.

FIM-43 Redeye 70mm


The M202 FLASH's in-game description: A rocket launcher loaded with four rockets that can be fired one after another, allowing the user to deliver massive firepower in a hurry. Anachronistic, as it was not developed until 1978.

M202 FLASH - 66mm

Carl Gustav M2

Powerful recoilless rifle with an optic for precise launches. Has a longer reload time than the other single-shot rocket launchers since there is a spent casing that needs to be removed before a new shell can be loaded. Available in 3 variants. The first, and default variant fires standard AT rounds. The second is a non-lethal version that fires Fulton Recovery Devices, allowing you to capture enemies or liberate prisoners from a safe distance away. The third, denoted by a yellow launcher body, fires HE rounds rather than AT rounds, and sacrifices some damage for extra area-of-effect.


X-FIM-92 Stinger

The prototype version of the FIM-92A Stinger, as it is known today. Although the concept was technically created in 1968, and initial testing began in 1972, full scale testing as prototypes were not developed until 1978 due to some flaws in the system. Its warhead is slightly more powerful, along with the lock-on computer, taking slightly more than one second to lock. Once fired, the missile behaves exactly like the FIM-43's.

FIM-92A Stinger - 70mm

M47 Dragon

Another usable heavy weapon is the M47 Dragon launcher. Although technically anachronistic due to being released in 1975 in real life, the small time frame between the two renders it inconsequential.

M47 Dragon - 140mm

Mounted weaponry


Hedgehogs were multiple spigot mortar weapons that were often launched by ships in Britain as depth charges. Several were fitted onto the Cocoon AI weapon, with the weapons system also being modified by Huey so as to allow it to operate on land (as Huey explained in a briefing file on the Cocoon).


Airsoft gas charger grenade

A grenade with a thin, smooth cylindrical body is used as the model for smoke grenades, almost the same model used in Metal Gear Solid 4. This appears to be based on a grenade-shaped gas bottle for Airsoft guns, such as the one shown below.

EAIMING "M116A1 Distraction Device Grenade," an airsoft gun gas charger built to resemble a hand grenade. "M116A1" is actually the US army's code for a simulation hand grenade with a paper body, used in training.

M112 C4 Demolition Charge

The M112 Demolition Charge is a remote detonated explosive with devastating power. Like in many video games, it can be detonated by shooting it, however the real-life C4 will not explode when shot at or set on fire, something that's ironically commented on in-game. It played a major role in-story with the Barricade mission, where Big Boss, its development having ordered by his second-in-command Kazuhira Miller in its use for the mission based on intel supplied by the FSLN child soldier Chico, used it to destroy a barricade at the Aldea de los Despiertos village to access a back route after an encounter with a tank forced him to find an alternate route due to its tank blast causing a train car to block the tunnel. It also was utilized during the alternate route mission, where MSF soldiers blew up a portion of a wall connecting Selva de la Leche and Selva de la Muerte's bottom cliff in the event that Big Boss needed a shortcut back. The C4 also ran on a timer, as hinted at by the ticking sounds. It also saw use in sabotage/equipment theft missions.

M18A1 "Claymore"

The M18A1 Claymore Mine appears as a weapon the player can set for ambushing enemies. It was also a major factor in some extra ops, including two dedicated to disarming claymores and two rescue missions where the prisoner is positioned near claymore mines.

M18A1 direction Claymore Mine

M15 Anti-tank Mine

The M15 anti-tank mine can be used to temporarily disable vehicles and kill anyone close to the explosion.

M15 Anti-Tank mine

M67 Hand Grenade

The standard frag grenades seen in game are M67 hand grenades. Apparently, even Soviet soldiers use the weapon instead of the Soviet standard-issue grenade RGD-5.

M67 Hand Grenade



The Tanegashima, a 16th-century Japanese muzzle-loading black powder matchlock arquebus, is an unlockable weapon ingame. Its low damage and single-shot nature coupled with a lengthy reload time makes it fairly useless in combat, but similar to its Metal Gear Solid 4 incarnation, each hit scored against an enemy soldier has a 1 in 3 chance of summoning a tornado that will send the soldier flying skyward (effectively removing him from the level), to be picked up by a helicopter and recruited into Militaires Sans Frontieres (Big Boss' ingame PMC).
