What appears to be a SIG-Sauer P229R with a stainless steel slide is used by Buddy (Jon Hamm) in the gun dealer shootout scene. It can be identified as a SIG P229 by the short slide, by the grooves on the slide and the reflection on the metal trigger.
Officers of the Atlanta, Georgia Police Department are shown to carry Smith & Wesson M&Ps as their standard-issue sidearms. This is quite accurate, as, in reality, the Atlanta Police carry M&Ps.
Inside the pistol cache on the bottom right is what appears to be some kind of 1911A1 variant with thin front and rear cocking serrations, three-hole trigger, rubber Pachmayr grips and (possibly?) a ring hammer. It is entirely possible that this is simply a Colt XSE or a similar variant with Pachmayr grips.
Dual SIG-Sauer MPX Pistols are wielded by Darling (Eiza González). The sound effects imply the MPXs firing in fully-automatic, despite obviously firing in semi-auto.
Buddy (Jon Hamm) is seen firing a custom AR-15 throughout the film. It is never seen closely enough to identify specifically, but it appears to have a 10.5" barrel, an aluminum free-floating railed handguard, a red-dot sight, a foregrip, Magpul furniture, a round trigger guard and what appears to be a 4-prong flash hider. Humorously, the firearm appears to fire in full-auto yet the sound effects seem to indicate semi-auto. This is the exact opposite error that Darling's MPX have.

Note eye protection! This film used authentic live-firing weapons, likely shooting blanks so the set was staffed with professionals and maintained gun safety.Error creating thumbnail: File missingOn the top of the illegal gun cache is the custom AR-15 variant which is used by Buddy later on in the film. Since the rifle fires in full automatic and was obtained by an illegal gun dealer, it can be fairly safely assumed that the upper is a civilian AR-15 while the lower was a military model with automatic capability or an illegally converted civilian one.Error creating thumbnail: File missingBuddy fires his AR beside Darling.Error creating thumbnail: File missing"This is all your fault."

"The Butcher", the illegal gun salesman (played by Paul Williams in a cameo) offers up a weapons cache for sale. Some of the weapons seen in the cache includes some pistols, submachine guns, assault rifles and grenades.
Error creating thumbnail: File missingInside the pistol cache (from left to right in the top row) is a first-generation Walther P99 (in single-action), a third-generation Glock 26 with an extended magazine baseplate, and what appears to be a particularly hideous custom Glock build done on a Polymer 80 frame. And on the bottom row, what appears to likely be the very same SIG-Sauer P228R that is used by Buddy (Jon Hamm) for much of the film, a third-generation Glock 17 and finally what appears to be some kind of 1911A1 variant with front cocking serrations, three-hole trigger, rubber Pachmayr grips and a ring hammer (possibly a Colt XSE).Error creating thumbnail: File missingInside the other gun cache are two Heckler & Koch MP7s, and what appears to be a SIG-Sauer SG-552 or 553 "Commando" and a SIG-Sauer MPX, likely the same one used later on in the film by Darling (Eiza González).Error creating thumbnail: File missingInside the other gun cache is an AKMS and a number of M26 "Lemon" grenades.Error creating thumbnail: File missingInside the other gun cache is an AKMS with wood furniture and what appears to be another AKMS that has been heavily altered cosmetically, to include a RIS. Note the lack of a muzzle device, meaning this could be a post-ban import civilian AK.Error creating thumbnail: File missingInside the other gun cache (from bottom to top) is a Colt Model 733, what appears to be some type of suppressed AR variant and the custom AR-15 variant which is used by Buddy later on in the film.
