.45 ACP Firearms

.45 ACP is the classic American big-bore pistol cartridge, prized for its heavy, slow-moving bullet and a century-long service pedigree. GunDNA catalogs 41 firearms chambered in it.

The format remains handgun-first: 34 of the 41 models are pistols — 1911s in the cartridge they were designed for, alongside modern polymer-framed duty guns — while 6 are carbines and a specialty build that carry the cartridge into long-gun roles. It is a caliber defined by stopping power and tradition rather than raw capacity.

Every model links to its full GunDNA profile with specifications, capacity, and compliance detail. Filter by type to focus on pistols or carbines, or read the .45 ACP caliber page for the cartridge's full story.
