Pros
- +Suppressor height is intended for optic backup and suppressor clearance on FN 509 tactical setups
- +Photoluminescent glow-dot front charges under any ambient light for daylight pickup
- +Larger rear tritium vials than the original R3D improve low-light alignment
- +Black nitride finish resists corrosion from sweat and humid duty carry
- +12-year tritium warranty backed by XS
Cons
- −Taller than factory sights and prints more on deep IWB carry
- −Glow-dot front is polarizing for shooters who want a clean post past 15 yards
- −Priced well above the factory 509 Tactical suppressor-height set
