P.S. Due to its low budget, this movie was filmed in low resolution, so quality of screenshots may be low.
The following weapons were used in the film Death Force:
M1911 style pistol
Unknown Pistol (Walther P38)
At least one gangster can be seen armed with this pistol, which resembles the Walther P38, but it's only a guess. All shots of this gun were very blurred due to movement.
Smith & Wesson Model 19
A Smith & Wesson Model 19 can be seen used by several characters.
Smith & Wesson Model 36
The Smith & Wesson Model 36 revolver is used by several criminals.
Colt Detective Special
The Colt Detective Special is a very popular handgun in this movie (a single movie prop was used).
J&R Engineering M68 Carbine (Mocked-Up)
McGee (Leon Isaac Kennedy) fires a J&R Engineering M68 Carbine with a fake drum magazine in several scenes. Numerous characters also can be seen armed with these mocked-up submachine guns. Some also feature the cooling barrel covers. It is difficult to explain these changes, but apparently they are meant to depict guns such as the Thompson M1928A1 and PPSh-41 (what is strange, because both are already in the film. But perhaps these scenes were filmed in other places, where these guns were not available).
M3 "Grease Gun"
The M3 "Grease Gun" appears in the hands of numerous characters.
The M1928A1 Thompson is a very popular firearm in this movie.
PPSh-style submachine gun
A PPSh-41-style appears in the hands of several characters. The general shape resembles a PPSh, but the screen gun has a tooooo long barrel).
A Remington 870 can be seen in the hands of one of the gangsters.
Arisaka Type 38
Hichigawa (Joonee Gamboa) holds the Arisaka Type 38 at one point. Several of Rico's guards uses similar looking rifles at the film's climax.
Winchester Model 70
Jordan (uncredited) fires a scoped Winchester Model 70 during the final scene.
Numerous soldiers are armed with the M1 Garand rifle.
At least one soldier uses a M2 Carbine.
Several of Rico's guards can be seen with unknown rifles. Identification is nearly impossible due to the low quality of the shots compounded by motion blur.
Browning Automatic Rifle
At least one soldier very briefly holds a Browning Automatic Rifle.
