Anybody have experience with Olight products?

I have an old Streamlight TLR-1 I’ve had for years and upgraded once to 500 lumens. I ordered an Olight weapons light rated to 1300 lumens at about half the price. Too good not to try. I’ll give a report when it comes in.

Most fit my Glock 19/23 but I’m having trouble with my SIG 320 X-carry with Wilson module. It needs a shorter light I guess.
