Notice: Minor spoilers are present on this page.
The following firearms make an appearance in the video game Mafia II:
The Colt M1911A1 is the standard pistol throughout the game. This weapon is seen being used by Vito, Joe and Henry in the game. The M1911A1 is Vito's favorite gun. Most "Made Men," including Joe carry the weapon in the back of their pants. Vito seems to prefer a shoulder rig, based on how he draws the weapon in cutscences. In the pre-release version it was called the "Cole 1911".
Custom Colt M1911A1
In Chapter 10 Joe and Vito use a special custom version with a 23 round magazine. Joe tells Vito not to lose it "because there are only two in the world", yet it can be bought at Giuseppe's. This version appears to be nickel plated with dark black wood grips, and appears as the "1911 Special".
Apparently, it was made in the likeness of the Colt Government Model which was specially modified by gunsmith Hyman Lebman, and owned by John Dillinger and "Baby Face" Nelson. However, the gun in the game differ in being semi-auto in game over the real gun's full auto, the in-game gun has a nickel finish over normal blued steel and a slightly smaller magazine capacity of 23 over the original's 25.
Smith & Wesson Model 10
The snub nose Smith & Wesson Model 10 appears as the ".38 Revolver" (the pre-release version called it the "S&W .38 Revolver M&P2"). Its the standard-issued sidearm of the Empire Bay Police Department and found in most gun shops early in the game . It is noted as a Smith & Wesson Model 10 by the cylinder release, which is clearly a push release and not the same as the Colt Detective Special's "pull-to-release" latch, and as well as the location of the screws on the frame. It also fires six shots, which eliminates the Smith & Wesson Model 36 as a possibility.
While based on the Model 10 snub nose, it oddly has some features from the anachronistic Colt DS 3rd generation, including an shrouded ejector rod, and wide target grips. The front of the frame also resembles an Astra Cadix as well.
The Mauser C96 first appears during a mission in Sicily, where it can be seen being used by Italian soldiers (although the main Italian handgun was then the Beretta M1934). Afterwards it can be bought at Harry's gun shop. It incorrectly uses .45 ACP rounds (only the Chinese Shansi Type 17 variant uses .45 ACP rounds) and is shown to be reloaded by inserting a detachable box magazine into the weapon from the underside of the magazine housing. The only C96 variants to commonly use a detachable magazine were select-fire models like the M712 Schnellfeuer, though there are some modern aftermarket kits to convert standard C96s to accept magazines.
Smith & Wesson Model 27
The Smith & Wesson Model 27 appears as the "Magnum" and takes .357 rounds (in pre-release version it was called "Seth & Winston .357 Magnum"). It is modeled with a full-length lug under the barrel, and without its adjustable sights. It also appears with a 4" barrel in the icon for a 3-star wanted level, despite the police only using their Model 10's.
Oddly it's also modeled with a 5-shot cylinder, although it accommodates 6 rounds, and uses the 6-round speedloaders. This is actually a relic of the pre-release version of the game, where it held five rounds, as can be seen in the early gameplay videos. By a strange oversight, after changing its capacity to 6 rounds, the models of the its speedloaders were changed, but not the model of the revolver itself.
The preferred submachine gun of the police officers in the game is the Thompson M1A1 with a 30-round box magazine. The fact that the Empire Police use this weapon during the 1940s section of the game is highly unlikely as this weapon was being issued to US troops fighting overseas.
The Thompson M1928 with a 50-round drum magazine is the main submachine gun of the gangsters. Thompson M1928 submachine guns are used by SWAT officers in the Joe's Adventures DLC, during the "Supermarket" mission. The M1928 Thompson in game is modeled with an M1/M1A1 Thompson stock and is incorrectly shown firing from a closed bolt. The Thompson M1928 is also depicted on the icon of the four-stars police wanted level, despite the fact that the police officers in the game use the M1A1.
Beretta Model 38A
The Beretta Model 38A is used by Italian soldiers in the training mission, and can be later bought at Harry's gun shop later in the game. Called the ".38 SMG" (.38 apparently meaning 9mm) in the game, it's also the only SMG to be to fired from the shoulder.
The MP40 is often used by enemy gangsters, and is more common than the Grease Gun. It has a surprisingly slow rate of fire and can be bought at Harry's. Bar owners on one side of town will use the MP40 if the player pulls a weapon in their bar.
M3 Grease Gun
The M3 Grease Gun is sometimes used by enemy gangsters and by, fittingly, the Greaser gang. Can also be bought at Harry's gun shop.
The M1 Garand appears in-game first in the prologue training mission and later on in gunshops across the city. The M1 Garand is also shown to be carried by Prison Guards during the prison mission, this is unlikely as it was being used overseas by US troops around the same time. Male burger restaurant owners will pull out an M1 Garand if Vito pulls out a firearm in their store.
The Karabiner 98k is used during the training mission, but can also be bought at Harry's gun shop in the late game. It grants one-hit kills against most enemies.
An MG42 machine gun is used by Vito first in the turorial mission and later in Mission 4 "The Buzzsaw," where he uses it to ambush a convoy of gangsters.
A Browning M2 Aircraft is seen on a Sherman tank in the first level, but is never used.
Remington 870 Field Gun
A Remington 870 Field Gun is used by Vito, gangsters, cops, and random shop owners. The shotgun in-game carries 8 rounds whereas it is modeled with a standard 4-round magazine. For some reason even if Vito fires once and reloads one shell, he always pumps the gun, but still retains the same amount of ammo. An advertisement on the in-game radio specifically calls the weapon as Remington 870 (in the pre-release version it was called the "Flemming 870"). Its an anachronism for the first five missions, as the Model 870 wasn't produced until 1950 while the early game is set in 1945. The raised rib was also a feature that wouldn't be added until later. A more accurate choice would be the popular Winchester Model 1912 or the Remington Model 31.
Mk 2 Hand Grenade
The Mk 2 hand grenade is the frag grenade used in the game, first in the prologue and then later purchasable from Harry's Gun store, referred to as the "Mk II Grenade."
Model 24 Stielhandgranate
During the grenade tutorial in Chapter 1, Vito tosses an Mk 2 frag grenade that lands on a box of Model 24 Stielhandgranates, causing a huge explosion.
Throughout the development of the Mafia II, there were many changes to the content, including cut missions, vehicles, and weapons. Here is a summary of the currently known weapons that have been removed.
The M14 rifle was to appear in the game, among the other firearms, but then it was removed. This is was apparently removed due to it being anachronistic for the game early to mid 50's settings, the M14 wasn't fully adopted and produced until 1959. The player can still use the M14, if you modify the game's files.
The Maxim M1910 machine gun was to appear in the Joe’s Adventures DLC, and intended for use in the final mission, "Cathouse," but was later removed, as well as many other pieces of content. You can see it only in the Test Scene (which can be unlocked with the help of modifications).
Model 24 Stielhandgranate
This is perhaps the most interesting removed weapon, as it is fully operational, and has its own HUD icon. It seems that originally they were to be actively used by the player (and, quite possibly, NPCs), but in the end the role of the M24 grenades has been reduced to only a single appearance in the opening level. The player can use the Model 24 Stielhandgranate if they modify the game's files.
Kar98k Sniper Rifle
Little is known about this removed weapon. Called the "K98 Sniper" in the game's files, no associated model appears to exist for it. What is most interesting is that the player can use this removed weapon if they modify the game's files. At the same time, it is clear that it does not have its world-model, any actual sniper function, nor does it have a HUD-icon. If used in-game, it is an ordinary Kar98k, but with increased accuracy and destructive power. This clearly indicates that this weapon was removed at an early stage of development.
Intratec TEC-9 Mini
For some very strange reason, the icon for Harry's gun shop is that of a Intratec TEC-9 Mini, despite the fact that this gun did not exist until decades after this game is set.
Bisley model Colt Single Action Army
The Bisley model of the Colt Single Action Army is seen on signs of the McClusky & Son guns shops.
A quartet of double-barreled Percussion Shotguns can be seen in the Vinci mansion.
