This LPA TRT Rear Sight is fully adjustable for both windage and elevation, and is engineered for compatibility with factory front sights in an effort to wring the utmost accuracy from a handgun with the least amount modification. The new TRT Series of Rear Sights have been strengthened to withstand the accelerated firing schedule of the serious competitive shooter, with a positive-click, recessed external adjustment screw design that has been tested for accuracy retention for more than 50,000 rounds. The Ultra-Low Mount sight body and blade bring the sighting plane down and closer to the hand for fast sight alignment, while the contoured profile and angle-radiused rear blade help to produce a consistent, snag-free draw from the holster. This TRT Rear Sight comes equipped with a Black, Horizontally Serrated Target Blade and is sized to fit a CZ Tactical Sport dovetail. Dovetail is 0.375".
