Like the title says there are more then a couple of them out their. I am looking at putting one on my new 5.7 and maybe a .45.
There's two kinds of RMR:
1. LED
2. Fiber-optic + tritium ("dual illuminated")
People are a bit meh on the duallies because they can wash out, but they also require no batteries. As far as durability, an RMR is the only kind of "micro dot" I would trust when mounted directly to a pistol slide, but I think the Burris Fastfire III is a higher value choice for rifles and shotguns.
The thing about mounting them to pistols is that doing it right is hard; you need to mill the slide, install taller suppressor sights, etc. Just dumping it on a mount doesn't work as well as you would think; if that's your plan, a C-More is more appropriate.
Speaking of which, I lust for that new M&P CORE, and it would be one of the few pistols I'd genuinely consider spending the money on an RMR for. Give it a threaded barrel, and it'd be an amazing suppressor platform.
One thing that seriously sucks about the battery-powered RMR (and many competitors) is that it must be removed from the gun (and/or its mount) to replace the battery, meaning your zero can shift when it is re-mounted. The C-More alternatives have a battery tray that pops out on the side. Be sure to check out the exact reflex sights that interest you in person first. The heavy tint on most of them is really annoying. Agreed with HT4 that the Deltapoint is more appealing in many ways, with clearer glass being one big reason why. Adjusting zero on the Deltapoint sucks, though. The clearest glass I've seen is on the JP Enterprises JPoint. Also check out the Burris Fastfire II and III.
I really like the Dual Illum RMRs. They are as bright as the light you are shooting them in. It only washes out if you are standing in a dark room shooting into a bright light.
