Slapped it on my Glock’s Picatinny in 3 seconds – rock-solid even during rapid fire. The 800-lumen punch lit up a dark warehouse 150m out, and the tail switch works flawlessly with gloves. Lock mode stops accidental activation in my patrol car. Ran it on CR123As for 2 weeks straight. IPX5 survived a downpour during a chase. Best $20 I’ve spent on gear.
