About this product

The CMMG Banshee MKG is a compact pistol built on the MkG platform and chambered in .45 ACP for shooters who prefer large-bore pistol calibers. This configuration features a 5 inch barrel, a CMMG RipBrace, and a CMMG EML4 M-LOK handguard with full-length M-LOK slots for aftermarket attachments. The MkG radial delayed blowback operating system is designed to reduce recoil impulse while allowing a lighter bolt and buffer system compared with traditional straight blowback designs. It is configured to accept Glock-pattern .45 ACP magazines and ships with one 13-round magazine.
