Key Features
- Multi-Footprint Optic Slide — Why it matters: You can mount a red dot from brands like Trijicon, Holosun, or Leupold without needing adapter plates, saving time and keeping the sight low to the bore.
- Spiral-Fluted Match-Grade Barrel — Why it matters: The fluting reduces weight and helps with cooling during extended strings of fire, while the match-grade rifling improves accuracy potential.
- Interchangeable Backstraps — Why it matters: You can swap the grip circumference to fit your hand size, which improves control and recoil management.
- Flat-Faced Aluminum Trigger — Why it matters: The flat face gives a consistent finger placement, leading to more predictable trigger pulls and better shot placement.
- Directional Serrations & Window Cut — Why it matters: The serrations give you a positive grip when racking the slide, and the window cut reduces reciprocating mass for faster cycling.
