During the opening scene, a Wells Fargo bank truck guard carries a Remington 870 when the guards are unloading money into the bank. Treasury agent Dave Foley (Richard Jordan) also carries one when his agents bust Jackie Brown during his M16 deal.
Artie Van (Joe Santos) uses a Colt Official Police in each of the bank robberies he pulls with Jimmy Scalise's gang. Scalise (Alex Rocco) himself uses one during the second and third bank robbery attempts.
One major plot point in the film involves Jackie Brown's sale of five M16 rifles to two aspiring bank robbers for $2,000 (including ammunition). The rifles are often referred to as "machine guns" throughout the film but are correctly identified as M16s more than once.
Eddie Coyle (Robert Mitchum): "I've never been able to understand a man that wanted to use a machine gun... The best all-around item is the four-inch Smith. You can lift it; she goes where you point it."
One of the Treasury agents with Foley during Jackie Brown's arrest carries a blued first generation Colt Detective Special. A Detective Special is also seen loaded by Jackie into the bag he sells to Eddie.
One of the .38-caliber revolvers Jackie sells to Coyle is a snubnose Smith & Wesson Model 36.

unidentified bolt-action rifle
One of Foley's Treasury agents carries a scoped bolt-action rifle when Jackie Brown is busted for possession of M16 rifles.
Coyle's final gun sale to Jimmy Scalise consists of "five Smiths, two Lugers, [and] a .357 Mag", with Coyle remarking about the latter that "you could hold up a bank with that thing yourself", charging $4,500 for the entire set. Despite playing an arms dealer, the Luger P08 is the only weapon Robert Mitchum is seen directly handling.
One of the "five Smiths" that Coyle sells to Scalise is a Smith & Wesson Model 10 which Scalise inspects then gives to one of his robbers to use in the third bank robbery attempt. Dave Foley (Richard Jordan) also carries one when he arrests Scalise's gang inside the house.
Dillon (Peter Boyle) uses a .22-caliber Colt Diamondback to murder Eddie Coyle after the Bruins game. After his young associate complains about the sound, Dillon reponds, "That's why I use a .22. I open up a .38 two-incher in here, you'll go right off the road."
