The CMMG Banshee FE Mk17 in 9mm is a short-barreled, magazine-fed modern sporting pistol built for shooters who want crossover versatility with their existing handgun magazines. At just 20.8 inches overall and tipping 4.5 lbs, it's one of the most compact 9mm options in the CMMG Banshee lineup—purpose-built for those seeking a PDW-style platform without the paperwork or tax stamp. The real differentiator is the Mk17 lower receiver: it runs Sig Sauer P320/M17/M18 magazines, meaning you can consolidate your 9mm magazine ecosystem across your carry pistol, duty carbine, and this platform all at once.
Built on CMMG's fixed ejector radial delayed blowback system, the Banshee FE delivers reliable, softer-shooting performance than traditional blowback designs. The 5-inch barrel with a 1:10 twist rate is threaded 1/2x28 and ships with CMMG's ZEROED Linear Comp to tame muzzle rise and blast. You get billet aluminum upper and forged lower receivers finished in Cerakote, an ambidextrous charging handle, and M-LOK mounting slots on the CMMG EML4 handguard for your optics and accessories. The CMMG RipBrace provides a solid cheek weld and control point, while the ZEROED drop-in trigger, selector with 60/90-degree safety, and integrated trigger guard round out a thoughtfully engineered package.
Whether you're a competitive shooter, home defender, or someone who just appreciates compact, modular 9mm platforms, the Banshee FE Mk17 bridges the gap between a duty pistol and a dedicated carbine without forcing you to duplicate your ammunition, magazines, or accessories. It's straightforward, reliable, and built for real use.
