Who It’s For
This pistol is for families who want a compact, easy-to-shoot .45 ACP that everyone can handle. It works for home defense, plinking at the range, or teaching new shooters the AR platform in a manageable caliber. The blowback action is smooth and reduces recoil, making it a good choice for youth shooters learning to manage a pistol-caliber carbine.
Pros and Cons
Pros: Reliable Glock mags, threaded barrel for accessories, compact size fits in a backpack or safe, low recoil for a .45 ACP, durable Cerakote finish.
Cons: Magazine capacity is 13+1, which is lower than some 9mm PCCs. The blowback action can be a bit snappy compared to delayed systems.

FAQ
Is the CMMG Banshee MkG .45 ACP 5-inch threaded 13+1 compatible with suppressors?
Yes. The barrel is threaded 5/8×24, which is a common thread pitch for .45 ACP suppressors. You will need a compatible suppressor and, if you choose, a SilencerCo piston or direct thread mount.
Can I use standard Glock 21 magazines with this pistol?
Yes. The Banshee MkG accepts Glock-pattern .45 ACP magazines, including standard Glock 21 magazines. The 13+1 capacity is standard, but extended magazines are available from Glock and aftermarket sources.
What is the difference between the MkG and the standard Banshee?
