8 Heads in a Duffel Bag
The following firearms are used in the film 8 Heads in a Duffel Bag:
Heckler & Koch USP
Tommy (Joe Pesci) uses a Heckler & Koch USP as his main sidearm. It changes hands several times, once used by Charlie (Andy Comeau) in an attempt to intimidate Tommy. It appears that the ejection port has been filed down to accommodate the firing of blanks.
A security guard at the Mexican airport draws his Beretta 92FS on the two hitmen.
A variety of guns can be seen inside Tommy's trunk in the airport parking garage, such as a Colt Detective Special, Colt New Service, Heckler & Koch USP, several other revolvers, and two sawed-off shotguns.
