A Beretta 92FS can be seen in the warehouse scene, when Tango (Sylvester Stallone) & Cash (Kurt Russell) are framed, being carried by one of the agents.Additional firearms can also be seen.
The S&W 36 is the revolver carried by Tango(Sylvester Stallone). He uses it in the initial scenes when firing at the truck transporting drugs. He appears to be able to hit the windshield, and make a tight group, from a long distance, despite the short barrel. He later uses it to shoot Perret.
A Remington 870 folding stock is used by Cash to get the information from Skinner. The shotgun has an extended magazine tube. The shotgun is also used by some of the prison guards when Tango & Cash escape.
This pistol can be seen being used by Cash (Kurt Russell). An error can be noticed in the roof scene. Cash pulls the slide back to put a round in the chamber, but the slides stays opened. In the following scene, the pistol is pointed at Requin's leg, but now the slide is locked. In the next scene however, the slide is open again.
The vehicle Tango & Cash "borrow" is fitted with a fictional 30mm gatling gun. Though rotary barrel auto cannons appear all over the world in similar calibers (mostly mounted on gunships) this is a purely fantasy weapon. However, during the final assault, a real M134 minigun is used for firing scenes.
looking at the trigger group (red markings for firing modes), i'd say its something from H&K
They are heavily mocked up H&K MP5 or MP5Ks. It drives me crazy how Cash yells "Clip" when he need a magazine. The mags looked like MP5 mags as well.
I understand the frustration and I know they are too very different things, but some of you guys really need to not be so stuck up about the whole clip/mag thing. The insults I've seen would make your eyes bleed.
It almost looks like an early version of the M29 OICW
Madsen machine gun
A Danish Madsen machine gun without a magazine is seen in this movie.
