CMMG Banshee MkG Pistol | .45 ACP | 5″ | 13rd | 45A150F-AB

The CMMG Banshee MkG is a compact .45 ACP pistol built on the MkG platform featuring a radial delayed blowback fixed ejector system. It pairs a 5-inch threaded barrel and CMMG ZEROED components with a forged MkG lower and billet upper for a robust, lightweight package. The pistol accepts Glock-pattern .45 ACP magazines and ships in an armor black Cerakote finish. For a close-quarters red-dot setup under $1000, consider the Holosun 507K for compact footprint and reliable performance.

This Banshee MkG balances compact handling with full-featured controls and an industry-standard accessory interface. The 5″ threaded barrel and linear compensator give flexibility for muzzle devices while the MkG platform and Zeroed components offer a configurable, user-focused control set appropriate for timed‑course competition and dedicated range training. The CMMG RipBrace and slim M-LOK handguard keep overall dimensions compact without sacrificing modularity.

Users commonly note that the Banshee is unusually compact for a .45 ACP pistol without sacrificing ergonomics or shootability, and many praise the MkG radial-delayed system for producing softer recoil impulses and improved controllability.
