I’ve been carrying an RMR pistol for 3 years. I’ve never had the emitter or glass get obstructed by anything with the exception of shooting with a suppressor. If you are using the optic correctly you can cover the front of the lense with duct tape and it is still 100% useable. Research “bindon aiming concept”I have been toting a MRPD on my 43X for the past couple of months, and while I enjoy it while shooting, I have concluded it is a worthless concept for me on my carry gun.
I am constantly struggling with it to keep the glass clear. Between deodorant that drops out of my pits, dead skin, hair, sweat, and lint, it only takes a couple of days for the lens to be so filthy is begins to obstruct the view. I understand that I am supposed to keep both eyes open and simply transpose the dot onto my target and not "look through the glass", but a few times the lens has been so bad I question if I would be able to pick up the dot.
I was speaking to a LE friend who told me about one of their guys drawing his gun to qualify and throwing the french fry that had been sitting in his RMR for who knows how long across the range. From what he told me, his department has banned optics on pistols due to the amount of crap they were finding on the glass, and how many were completely obstructed.
For a range gun, I am a huge fan. For a carry gun, it's not for me. If I wanted to have to jack with keeping my gun "clean" every couple of days, I wouldn't be carrying a Glock.
