Keeping Traditions Alive Since 1953

CMMG built its reputation on the .45 ACP MkG, and the request they kept hearing afterward was simple: same gun, 9mm, feed it from Glock double stacks. The Banshee MkGs is the answer. It ships with a 33-round magazine, and since it runs standard Glock-pattern double stack mags, spares are affordable, available everywhere, and there is a good chance you have a drawer full of them already.
The heart of this gun is CMMG's Radial Delayed Blowback system. Instead of relying on a heavy bolt slamming back and forth like a straight blowback design, the rotating bolt delays the action and lets CMMG run a lighter bolt with less reciprocating mass. The result is a noticeably gentler recoil impulse, faster follow-up shots, and less beating on the gun over time. It plays nicely with suppressors too, and with a 1/2×28 threaded muzzle already wearing a Zeroed linear compensator, adding a can is about as easy as it gets.
The 8 inch 4140CM barrel carries a 1:10 twist and a durable finish under Satin Black Cerakote, mated to a billet 6061 upper and a forged 7075 MkGs lower. CMMG's Zeroed parts come standard across the board: a drop-in single stage trigger, ambidextrous charging handle, ambi 60/90 degree safety, and their comfortable pistol grip. The EML handguard gives you M-LOK real estate on the sides and bottom plus slots between the top Picatinny sections, so lights, hand stops, and sling mounts all have a home. The flat top is optics ready with no sights installed, which is the right call since most folks are dropping a red dot on a gun like this anyway.
At 23.7 inches overall and right around five pounds, this is a legitimately compact package. The six-position RipBrace extends with a quick pull, so it stores short and deploys fast. Home defense, range days, PCC-style drills, truck gun duty, it covers all of it, and CMMG backs the whole thing with their lifetime quality guarantee.
It runs standard double stack 9mm Glock-pattern magazines, and one 33-round mag comes in the box. That includes factory Glock 17, 19, and 33-round mags along with quality aftermarket options like Magpul GL9 PMAGs. Since these are some of the most common pistol mags on the market, keeping spares on hand is cheap and easy.
Yes. The 8 inch barrel is threaded 1/2×28, which is the standard pitch for most 9mm suppressors, and the Zeroed linear compensator spins right off. CMMG's Radial Delayed Blowback system was designed with suppressed shooting in mind, so it runs reliably with a can attached without the excessive gas blowback you get from straight blowback guns.
No sights are included. The flat top Picatinny rail is optics ready, so plan on adding a red dot, a low power variable optic, or a set of flip-up backup sights. Most owners pair a gun like this with a compact red dot for fast target acquisition at PCC distances.
Traditional blowback PCCs need a heavy bolt and stiff buffer to stay closed during firing, which makes them snappy and rough shooting. CMMG's rotating bolt delays the action opening, allowing a much lighter bolt and a noticeably softer recoil impulse. That means quicker follow-up shots, less wear on parts, and a smoother experience overall, suppressed or not.
