This is my 7th flashlight from this brand. I have 3 of them mounted on firearms. There’s probably no need to write about the quality. It is very good. The quality-to-price ratio is perfect. This model is mounted on a Glock 45 Gen 6. It fits perfectly. You only need to change the plate, which is included in the set. It also looks great. A huge plus for the ability to adjust the light beam and for USB-C charging.
