The CMMG Banshee MKG is a modern take on the classic .45 ACP pistol caliber—compact, hard-hitting, and built for shooters who want that legendary American cartridge in a package that doesn't hog belt real estate. At 5 inches of barrel length and 20.8 inches overall, this is the shortest Banshee variant CMMG offers in .45, yet it refuses to compromise on ergonomics or the handling characteristics that made the platform popular in the first place. Whether you're running suppressed at the range, looking for a backpack gun for backcountry self-defense, or just want a tack-driver that won't wear you out during extended shooting sessions, the Banshee MKG delivers practical performance in a genuinely portable footprint.

Built on CMMG's MKG platform, this .45 ACP uses a radial delayed blowback operating system—a design that keeps recoil manageable and cycle times controllable without the complexity of a traditional short-stroke piston. The 4140CM barrel (1:16 twist) is paired with CMMG's linear compensator threaded at 0.578 x 28, so it pairs naturally with common .45 suppressors if that's in your future. The billet aluminum upper and forged lower are cerakote finished for protection against the elements, and the EML4 M-LOK handguard gives you straightforward real estate for lights, lasers, or whatever mission-specific gear you're running.

The controls are ambidextrous where it counts—charging handle, safety selector (60/90 degree), and that drop-in ZEROED trigger are all designed for left or right shooters. A CMMG RipBrace handles the rear, and the magazine takes standard Glock 13-round .45 ACP mags, so ammunition logistics stay simple. At 4.4 pounds, it's light enough to carry all day without turning into dead weight, making it a genuinely practical option for hunters, sport shooters, or anyone who wants a no-nonsense .45 ACP in a format that respects the modern tactical rifle experience.
