LAPD SWAT members including Jack Traven (Keanu Reeves) and Harry Temple (Jeff Daniels) keep M1911A1 pistols as their sidearms in the film. Since LAPD SWAT wanted something less limiting then revolvers after the North Hollywood shootout, they chose M1911A1 pistols. These 1911 models varied differently for each user, many of which where handguns originally confiscated from criminals and tricked out by the department "gun cage jockey" who would turn the guns into tactical weapons. These were also the first guns to be fitted with frame mounted flashlights. After deciding to have the department issue these guns so the officers wouldn't have to buy them, they tested several models until they decided upon the Kimber Custom TLE II as their sidearms. Since this film is before the issue of these guns, the 1911s can be any type of model.
Heckler & Koch HK94A3 (chopped and converted)
Jack and Harry are seen using Heckler & Koch HK94A3 collapsing stock civilian guns with 16" barrels chopped and converted to resemble MP5A3s with Surefire light dedicated forends. They can be noted as HK94s instead of MP5A3s because of the lack of barrel lugs, a push-pin set and a paddle magazine release behind the magazine.
Heckler & Koch HK94A2 (chopped and converted)
A SWAT member following Harry into Payne's house is seen using a full-stock Heckler & Koch HK94A2 16" barrel civilian gun chopped and converted to resemble an MP5A2 with a Surefire light dedicated forend.
Chrome Heckler & Koch MP5K
Howard Payne (Dennis Hopper) uses a Chrome-Plated MP5K.
Unknown Detonator
Howard Payne (Dennis Hopper) uses a 'Hand Grip' remote detonator.
Smith & Wesson 4004
Jack Traven (Keanu Reeves) keeps a Smith & Wesson 4004 chambered in .40 S&W as his off-duty sidearm in the film. This pistols downfall was its aluminum alloy frame, which cracked easily after long firing due to weakness.
MPM2008, this gun's picture is impossible to find. Can you check the armory for one? - Gunmaster45
Mossberg 500 Mariner
Howard Payne (Dennis Hopper) uses a Mossberg 500 Mariner fitted with a pistol grip with the barrel sawed down to 16" to shoot at Jack and Harry through the roof of the elavator (which firing a shotgun in an elavator would result in permanant hearing damage almost instantly). When Harry falls through, he continues to fire a Jack, taking the elavator to the top floor to force Jack to jump in. When he does, he sticks the shotgun in his face and pulls the trigger, only to find the gun is empty. In reality, his Mossberg is a six shot (including one in the chamber), not eight like it is portrayed in the film.
Smith & Wesson Model 60
A passenger on the bus draws a Smith & Wesson Model 60 on Jack when he first gets on the bus until Ortiz (Carlos Carrasco) tackles the gunman, resulting in a stray shot which hits Sam (Hawthorne James), the bus driver.
Unknown Sniper Rifles
The LAPD SWAT snipers waiting for Payne to take his money watch the exchange site with sniper rifles, all too far away for clear identification. The one closest seen appears to be a Remington 700PSS.
Heckler & Koch SP89 (mocked up as MP5K)
Howard Payne (Dennis Hopper) uses a nickel plated Heckler & Koch SP89 made to look like an MP5K by adding the MP5K foregrip and converting it to full-auto. It can be noted as an SP89 instead of an MP5K due to the lack of a paddle magazine release behind the magazine and lack of a push-pin lower reciever.
