While there are a number of pistol mounted weapon lights on the market, Olight is fairly new to the game. I’ve had the chance to run their Valkyrie PL-MINI for awhile on a Gen 5 Glock 19.
As far as weapon lights, the controls are pretty intuitive and the beam isn’t bad, especially for indoor use. I’d have to say my favorite thing about the PL MINI Pistol Light is the fact it uses a lithium polymer battery. It makes the light housing low profile and easy to charge.
Unfortunately, due to the odd sized light body, the tac light suffers by not being well supported in the market. What I mean is, it can be a hassle to find a holster to fit this light. I think it is a great light for a nightstand gun, or even EDC (Every Day Carry) if you manage to find a good holster for it.
