Works great! Had an issue sourcing screws as the included holosun screws were the wrong pitch for the Beretta apx a1 tactical and the mounting plate is proprietary to Beretta.
Once those were obtained, it mounted up fine. Also purchased a opticgard in fde to match the pistol rather than paint the optic.
Holosun runs great. Nice crisp reticle, holds zero, big window.
