A pair of Smith & Wesson Model 15 revolvers are one-armed Arlen's (Suki Waterhouse) weapons of choice. These revolvers have different grips. However, she always uses only one revolver at time. Considering the fact, that she can't quickly reloads her sidearm due the obvious reasons, carrying a single revolver is a rather strange choice.
Arlen holds a Single Action Army akimbo with her Smith & Wesson on the movie poster, but it does not appear in the movie itself. This is possibly from a deleted scene.
Nearly all the Dream girls (played by Alina Aliluykina, Ashleigh Biller, Irene Guindal, Nina Mansker, Emily O'Brien, DaLaura Patton, Lana Walling, Allison Gordon, Stephanie Nauli and Ndea Williams) and guards are armed with IMI Uzi SMGs.
A cartoon M16-style rifle can be seen on a sign for a gun shop.

While it was intended for the AK to use all stamped parts for cost reasons, the Soviet metalworking industry was simply not ready to do this at the time, and the high rejection rate of the early stamped AK receivers led to a switch to milling that lasted until the introduction of the AKM.Error creating thumbnail: File missingSix pistols are seen among the AK rifle.
