Hey Guys - I've recently run into the exact same issues on all 4 of my RMR02's. They were all done by Mark after he originally did my 19. His attention to detail and craftsmanship is second to none and that's why I had him do another 3. He's the best in the business as far I'm concerned and these issues are 100% on Trijicon. Here's what's happened:
When, I first ran my Glock 19 back in January, I lost the sight after the 37th round thru it. It came back on the 41st. I haven't had another issue with it until today.
I ran the 17, 34, 19 and my buddy ran the Sig today and here are the results/issues.
Red dot went out and came back on the following strings - 6/7, 15/17, 32/34, 41/42, 48/51. I then had it go out on the following string counts and was able to bring it back by hitting the RMR with the palm of my hand. 57, 63, 71, 76. All of these happened after firing the previous full string and always occurred after I picked the weapon up to start the next string.
6/7, 12/13, 18/20, 26/27, 34/37, 44/47, 52/53.
This string disappeared and returned after being struck - 57, 66, 71, 77, 82
Glock 19: 21, 29, 34, 42, 51. All returned at the beginning of the next string.
Sig - Went out on about the 20th and returned on the 23rd.
I'm a huge fan of this platform and I'm certain the reliability issue will be solved soon. In plan on contacting Trijicon after speaking with Mark. If anyone has any insight, it would be greatly appreciated.
Cheers guys. Shoot straight and be safe!
