The following weapons were used in the film The Mighty Quinn:
WARNING! THIS PAGE CONTAINS SPOILERS!
Smith & Wesson Model 10
Xavier Quinn (Denzel Washington) carries a Smith & Wesson Model 10 that he pulls when he finds a suspect's gun.
Smith & Wesson Model 10 HB (Heavy barrel) Revolver (Post 1950s Model) - .38 Special. Later incarnations of the Model 10 had a non tapered Heavy Barrel, which leads it to be commonly mistaken for a .357 revolver.
Heckler & Koch P9S
Jose Patina (Alex Colon) is caught carrying a concealed Heckler & Koch P9S fitted with a suppressor. Quinn fires the weapon into the wall near Patina's head to interrogate him, and it is later used by CIA agent Miller (M. Emmet Walsh) to execute Patina.
Heckler & Koch P9S, 45. ACP
