Doesn't work very long - Trijicon RM06 RMR Type 2 1x16mm Reflex Red Dot Sight

Got this sight a week or so ago, and mounted it on a new Glock 34 MOS using the Glock supplied mounting plate. I had to order a mounting kit from Trijicon to get the proper length mounting screws and a sealing plate. Went to the range to sight it in which turned out to be pretty easy. Fired about 50-75 rounds and things went great. Then I fired a round and the LED disappeared. I bumped the gun a couple of time and the LED came on. Fired again and the LED went off. Bumped again it came back on. This repeated several times so I gave up. I contacted Trijicon support today and am waiting on a reply from them on what to do. In reading some other reviews, this has happened to some other purchasers as well, so, I suppose it is some sort of defect in the sight. I like it when it works, but, if it fails after a shot, it's not acceptable. I'll update after hearing from Trijicon.
