Colt M1911 / M1911A1

The Colt M1917 is a six-shot revolver chambered in .45 ACP developed for the United States military. It is based on the Colt New Service frame and uses half-moon clips to chamber rimless .45 ACP cartridges. The M1917 was adopted as a stopgap sidearm during World War I due to M1911 production shortfalls. It features a swing-out cylinder and double-action trigger mechanism. The revolver served alongside the M1911A1 through both world wars and into the Korean War. It is a rugged and reliable revolver that helped standardize the .45 ACP cartridge for US forces.

The Smith & Wesson Governor is a six-shot double-action revolver chambered to accept .410 bore shotshells, .45 Colt, and .45 ACP cartridges (with moon clips), offering the widest ammunition versatility of any revolver ever produced. Built on S&W's scandium-alloy Z-frame for lightweight durability, the Governor features a 2.75-inch barrel, Tritium front night sight, and a matte black finish. It was developed as Smith & Wesson's direct response to the Taurus Judge, which had dominated the multi-caliber revolver market since 2006. The Governor's ability to fire three distinct cartridge types makes it exceptionally versatile for personal defense, and its six-shot cylinder provides one more round than the competing five-shot Taurus design.

The Smith and Wesson Model 325 is a lightweight N-frame revolver chambered in .45 ACP. It features a scandium alloy frame combined with a stainless steel cylinder and barrel. The 325 was designed as a carry-friendly .45 ACP revolver for defense and competition. It uses moon clips to load and eject rimless .45 ACP cartridges reliably. The Model 325 was produced in several variants including the PD (Personal Defense) and the Thunder Ranch special edition. Its six-round capacity and powerful caliber make it a favorite among revolver enthusiasts.
