Ronnie Wingate (Jon Gries) keeps a Smith & Wesson Model 67 in his pants, often showing it off to try and intimidate people. In the book, this gun is the AMT Hardballer, that Bo later "borrows" and uses to shoot Yayo.
AMT Backup
Ray Bones (Dennis Farina) uses a AMT Backup to shoot Ronnie Wingate, then places the gun in the hand of Harry Zimm (Gene Hackman), who is blamed for the shooting. When Ronnie (Jon Gries) realizes too late this his trusty Smith & Wesson 66 is in his belt, while Ray's is in his hand, he tries to disconcert Ray by referring to Ray's as a "Wop 9... the Fiat of guns, always jammin' on you at the wrong time," to which Ray responds by shooting him four times with the AMT.
Colt Gold Cup National Match
Bo Catlett (Delroy Lindo) uses a Colt Gold Cup National Match during the film (N.B. In the book, the weapon Ronnie shows off, which Bo later "borrows" to shoot Yayo and threaten Chili, is a long-slide AMT Hardballer).
Martin Weir (Danny DeVito) fires a stainless Desert Eagle with a scope attachment in Chili's film, constantly pressing the magazine release instead of the trigger. The technical consultant, Bear (James Gandolfini), takes it from him and looks at it.
