I just got a set of Meprolights installed on my Glock36 the other day, based on some reccomendations I got from this board and I wanted to say thanks. I was going to go with PT night sights that were available at a local gun store since I didn't even know about the Mepros'. I'm very impressed with them though, after comparing them to the PT's you can tell the Mepros' are brighter and sharper. I've been shooting into our pond at GITD ping-pong balls at night, it's alotta fun and the sights work excellent. Anyone thinking of getting night sights should check 'em out!
