Equipped with a 5” barrel, this BANSHEE™ is one of the shortest 9mm pistols CMMG® offers. What sets this BANSHEE apart is the Mk17 platform lower which is designed to use Sig Sauer P320/M17/M18 pattern magazines. Being able to use handgun magazines in a pistol caliber carbine or personal defense weapon allows shooters to use their existing collection of magazines, mag pouches, and other accessories.

From the quick deploying RIPBRACE®, to the stylized receivers and EML™ handguards, every BANSHEE is tailor-made to be the personal defense weapon you can always depend on. New EML4 handguards feature M-LOK® slots at 3, 6, & 9 o’clock positions and a full length picatinny top rail for accessories as well as an integrated handstop.

  • Radial Delayed Blowback™ Operating System - Originally developed for the .45 ACP MkG platform, CMMG has adapted our Radial Delayed Blowback system across our pistol caliber lineup to create pistols and rifles with a softer recoil impulse and reduced bolt weight compared to traditional straight blowback systems. Check out our CMMG Resources article & video to learn more about what sets Radial Delayed Blowback apart.
  • Mk17 ZEROED parts and accessories – The AR platform is well known for its capability for customization but picking the right parts doesn’t have to be a nightmare of homework. Everything from the RIPBRACE to the full kit of ZEROED parts and accessories are made here in the USA with quality and attention to detail that is second to none and Each BANSHEE Comes Equipped With A Slew Of ZEROED Parts Standard, Including:
