The CMMG Banshee MKG is a .45 ACP pistol built for shooters who want AR-pattern controls and ergonomics in a compact, maneuverable platform. This fixed-ejector handgun combines CMMG's Radial Delayed Blowback operating system with a proven cartridge—one with a century-plus track record—and packages it in a form factor ideal for close-quarters defense, duty carry, and shooters who prefer .45 ACP ballistics. At 8 inches of barrel length and 23.8 inches overall, it balances firepower and portability without the tax stamp and paperwork of an SBR.
The Banshee MKG runs Glock-pattern .45 ACP magazines, so you're not locked into a proprietary supply chain. The receiver is forged 7075-T6 aluminum—the same alloy used in aircraft—while the upper is billet 6061-T6. The CMMG EML7 handguard is fully slotted with M-LOK on the sides and bottom, plus additional M-LOK mounting between top Picatinny sections, giving you serious real estate for lights, lasers, and other must-have gear. Everything from the charging handle to the safety selector carries the CMMG ZEROED family of components, including a 60/90-degree selector for fast, ergonomic manipulation.
The RipBrace offers quick deployment and the confidence that your personal-defense setup is field-ready. Finish is Cerakote in Armor Black—durable, corrosion-resistant, and ready for hard use. Weight comes in at 4.8 pounds, so you won't feel it dragging at the hip or on a sling during extended carry. Whether you're a .45 purist outfitting a truck gun, bedside option, or the next step up from a duty pistol, the Banshee MKG delivers rifle ergonomics and customization in a handgun that doesn't compromise on power or control.

We cannot advise on legality or regulatory status. Federal law and ATF guidance on braced pistols changes, and state and local laws vary significantly. Consult a firearms attorney in your jurisdiction before purchase.
Yes. The EML7 handguard features M-LOK slots on the sides, bottom, and top (between Picatinny sections), providing extensive real estate for lights, lasers, vertical grips, and other accessories. The upper also includes a full-length Picatinny rail for optics or co-witness sights.
The barrel features a 1:16 twist rate. Consult ammunition manufacturer data and ballistic resources for compatibility with your specific .45 ACP loads; twist rates are rarely a limiting factor with .45 ACP, but always verify ammunition performance in your firearm.
