Some of the Rancho Cucamonga Police carry Beretta 92s when they arrive at the Joker Brothers House at the ending. The record store owner Pinky (Clifton Powell) notably carries a custom nickel plated model with custom grips.
The guns circled in green are some sort of Glock variant (17 or 19). The shotgun in the blue circle is a black Remington 870. The stainless Beretta appears to be a a custom Beretta 92FS with a stainless slide. Also, these are not Beretta 92s. Beretta 92s have a rounded trigger guard, a frame mounted slide stop safety, and a bunch of things these Berettas lack (we don't call Beretta 92s "M92s" as they are not militarized versions of Berettas). Thus, the pistols are Beretta 92FSs.- Kenny99 21:42, 23 August 2010 (UTC)
Glock 17
Some of the police as well as Lil' Joker (Lobo Sebastian) carry Glock 17s.
Uncle Elroy (Don "D.C." Curry) carries a Smith & Wesson Model 627, while sneaking into the Joker house. He humorously explains he only has two bullets in it, but its better than nothing.
Remington 870
Some of the police officers that converge on the Joker house are armed with Remington Model 870 Shotguns
Norinco Type 56
Joker (Jacob Vargas) carries a Norinco Type 56 Assault Rifle towards the end, it changes hands a few times.
