Illinois Gordon (Chi McBride) carries a nickel Smith & Wesson Model 10 snubnose revolver, which he gives to Bumpy before his death at the hands of Capt. Foley.
Illinois Gordon (Chi McBride) gives his cousin Bumpy Johnson (Laurence Fishburne) a Colt Police Positive revolver, which he uses throughout the entire movie to take over Harlem. At one point, Bumpy's girlfriend Francine (Vanessa Williams) is forced to shoot assassin Albert Salke (Mike Starr) with the revolver.
Queen Stephanie's bodyguard, Tee-Ninchy (Eddie Bo Smith Jr.) caries a sawed off Ithaca 37 as his weapon of choice. He carries it with him, (and nearly uses it) during the meeting between Queen Stephanie, and Dutch Schultz. He also uses it to kill several hitmen during the attempted hit on the Queen before being shot to death. When Bumpy and Whispers gain the upper hand during the shootout, Bumpy picks it up and uses it to (unrealisticly) set a nearby truck ablaze. Before the hit, one of the Queen's guards can also be seen holding this weapon.
Many of the Harlem gangsters in the film use M1911A1s. Whispers (Paul Benjamin) carries two, one on each hip, that he draws several times. Dutch Schultz's bodyguard, Lulu Rosencrantz (Ed O'Ross) carries a 1911, which he eventually uses to shoot his boss in the Palace Chop House bathroom.
Dutch's gunmen use Thompson M1928s during their attempted hit on the Queen and Bumpy. After killing one of the hoods, Bumpy picks up the Thompson and fires back at them with it.
Albert Salke (Mike Starr) and Jules Salke (Beau Starr) use a "suppressed" Colt Detective Special to kill the guard at Bumpy's building during their attempted hit, following the classic movie myth of having a suppressor work on a revolver.
To be clear, there are models of supressed revolvers that exist however they must be built from the ground up to be supressed, simply putting a suppressor on normal revolver does not work due to gas escaping from the gap between the cylinder and the barrel. Therefore, calling suppressed revolvers a myth is only partially correct.
Bub Hewlett (Clarence Williams III) carries a sawed-off Remington 870 when Dutch's men raid the apartment at the end. He also uses one during the attempted hit on Queen Stephanie before tossing it away. Several other sawed-off 870 shotguns are used, some without their stocks.
