CMMG is introducing an entirely new line of ultra compact short barreled rifles and pistols called the Banshee.

Designed to offer the shortest barrels possible in 9mm, .45 ACP, .300 BLK, and .22 LR, they represent the state-of-the-art in design and function.

Incredibly light weight and portable CMMG’s Banshee meets the growing call for pistols and SBRs designed for today’s shooters.

Banshee Build

CMMG’s pistols use the Gear Head Works Tailhook Mod 2 Brace. Each comes standard with an ambidextrous charging handle, safety selector and sling plate.

CMMG’s RML4 M-LOK Handguard is used along with a Magpul MOE grip. All are coated in CMMG’s Premier Cerakote finish.

The 9mm and .45 ACP Banshees feed from factory Glock magazines and utilize CMMG’s patent pending Radial Delayed Blowback operating system.

The benefit of the Radial Delayed Blowback system is that it allows CMMG to use a lighter buffer and carrier than the typical straight blowback design. This reduction in reciprocating mass ensures that both the 9mm and .45 ACP version of the Banshee are easily controllable.

Range Results

The Banshee is one of the softest shooting pistols ever, even when used with the hottest .45 ACP loads.

Accuracy was excellent with half-inch groups from a rest at 25 yards.

At 50 yards, groups using the Sig Sauer Romeo 3 RDS were still under an inch. Using the Alpha Dog Suppressor it remained very light weight and easy to handle.

Reliability was excellent with very little excess gas in my face when suppressed. The Gear Head Works Tailhook Mod 2 brace was one of the most versatile used to date. It didn’t add any weight allowed for fit to larger forearms and use from most any position.

If you are looking for an excellent pistol or SBR for defense, range time, or you favorite PCC competition these look to be just the ticket so make sure you take a very close look.
