Won this at an event this summer, don't see myself using it. Brand new in the box, never mounted, only pulled out to throw the batteries in and see the pretty red light. Model LG-629 for Glock 29 and 30 is what it says on the box, but I have no idea if it will work with other frames. Not sure if it needs a different pin for the grip, but it doesn't have one in the box. It never did when I got it, I'm sure they aren't hard to come by though. 199 New on amazon, 175 buys it.
