Duty use ready - Holosun HE509T Reflex Optical Red Dot Sight

Purchase this optic, mounted it on Glock model 45 with CH base plate, sited it in and took it to a red dot instructor class. During the 3 day class, the complete weapon system was flawless and my estimated round count was over 1200 rounds during the class. The optic appears to be sturdy and point of impact never shifted. No issues whatsoever, even when subjected to water purposely poured over the lenses prior to shooting and setting the optic up for failure drills. The instructor uses this exact same optic on an STI staccato, which he carries on duty for a police department. So far nothing but praise for this optic, CH base plate and Glock model 45 pistol combination.
