The slide wears a black Nitron finish and Spectre-style lightening cuts. Sight configuration features a night‑sight front mounted to the compensator and a plain black rear notch for a consistent sight picture relative to the comp.

A flat, skeletonized, TiN‑coated trigger complements the striker‑fired, semi‑automatic action. An accessory rail is integrated into the frame for mounting compatible lights or accessories.
