CMMG Banshee .45 ACP

The CMMG Banshee .45 ACP is a compact pistol built on the MkG platform for range use, personal defense, and competition. It uses the MkG Fixed Ejector Radial Delayed Blowback system to provide a reduced recoil impulse compared with traditional straight blowback designs. The 8-inch threaded barrel and compact overall length make it suited to controlled-range shooting and versatile duty-style applications.

The Banshee pairs lightweight, durable materials with modern ergonomics. The upper is billet 6061 T6 aluminum and the lower is MkG forged 7075 T6 aluminum finished in Cerakote, while the CMMG EML7 M-LOK handguard provides full-length M-LOK slots for accessory mounting. Controls and interfaces include a ZEROED ambidextrous charging handle, an ambidextrous safety, and a ZEROED drop-in single-stage trigger for consistent operation.
