Key Features

- HI-VIZ fiber optic front sight – WHY IT MATTERS: Picks up ambient light for a bright aiming point in low-light conditions, a critical edge in a defensive encounter.
- Double-action-only trigger – WHY IT MATTERS: Provides a consistent pull every time, reducing the chance of short-stroking under stress and improving shot placement.
- Titanium cylinder – WHY IT MATTERS: Resists corrosion and keeps weight to 12 ounces while safely containing .357 Magnum pressures.
