The CMMG Resolute in .45 ACP uses the Radial Delayed Blowback system to manage the heavy .45 ACP cartridge in a 16-inch carbine format. Like the Banshee .45 ACP but in a full-length carbine rather than pistol configuration, it provides the familiarity of .45 ACP ballistics in an AR-15 ergonomic package. CMMG's Glock 21-compatible magazine adapter accepts standard G21 mags. Type: Pistol Caliber Carbine Action: Semi-Automatic Caliber: .45 ACP Capacity: 26 Year introduced: 2019, USA Weight: 70 oz Overall length: 33.5" Status: Active Intended use: Home Defense, Competition, Range Use
