### Features
The 8-inch barrel gives good maneuverability in tight spaces without the extreme velocity loss you'd see from something even shorter. Forty rounds on tap is genuinely useful for competitive stages or home-defense drills where reloads interrupt timing. The matte black finish holds up well to handling and resists glare.

The 5.7x28mm caliber pairs well with the Banshee platform: recoil is light enough that fast follow-up shots are easy to manage, and the round still carries useful energy at realistic engagement distances.
