Lowest quality streamlight product - Streamlight Glock 43X/48 MOS TLR-6 Tactical LED Weapon Light

I have streamlights on most every weapon I carry or use on a regular basis. Put this on a G48 MOS. The fit is great & the item felt constructed well. I fired about 20 rounds & the laser went out on its own. Then it would not turn on with a button press. Had to open battery door and close before the button would turn it back on. Fired 3 more rounds & it turned off again. This time the button turned it on. But now it turns off with every subsequent shot. Never had this happen with any other Streamlight. I am returning.
