The CMMG MK17 Banshee accepts SIG M17 and P320 magazines. The Banshee design gives you the firepower you need in a compact and lightweight platform.

The Banshee Mk17 uses the Radial Delayed Blowback system originally developed for the .45ACP MkG platform. This system is ideal for pistol caliber platforms and allows for softer recoil impulse and bolt weight compared to the traditional blowback system.

This model accepts SIG P320/M17 magazines.
