Key Features

- Optic-Ready Ported Slide — Why it matters: Cuts down muzzle rise for faster follow-up shots and accepts most red dot footprints with the included adapter plates.
- Suppressor-Height Tritium Sights — Why it matters: Co-witness through your optic or see the dots clearly in low light without upgrading sights.
- Expanded Magwell — Why it matters: Speeds up reloads on the clock or under stress, especially with the 21-round magazine.
- Interchangeable Backstraps — Why it matters: Adjusts grip angle for smaller or larger hands, improving control and accuracy without buying a new frame.
Who It’s For
This pistol is for EDC carriers who want a suppressor-ready, high-capacity 9mm with an optic cut from the factory. It also fits competition shooters who need a threaded barrel for a compensator and a magwell for fast reloads. If you run a red dot and a can, this saves you the cost of slide milling and barrel threading.
