The RMR's blue tint and edge distortions are irrelevant if you use it like you're supposed to.
Stop trying to see the world through the little window. Stop trying to focus on the dot: it makes you slow as fuck and draws you to try to see the world through the tiny window.
Keep your head erect. Lose the god damn tactical turtle 90's pose. Use both eyes to focus on the target and bring the pistol UP to your face. The dot will be crisp and superimposed on the target and the RMR's blue tint, little window, and minor edge distortion will become nearly invisible.
Oh yea, you'll have to unfuck your presentation out of the holster or you'll never find the dot.

My carry gun has an RMR, but I also have an SRO on another pistol. On the subject of what to carry, let's get fucking real. If you're joe average ccw (like most of us) your pistol will live in the holster 99% of the time and the chances of dropping one are zero unless you're a complete klutz. Because of that, get an SRO. While the housing isn't as rugged as the RMR's, the electronics most certainly are.
If you're a cop, or someone else who will actually go looking for a fight armed with a pistol, then get an RMR
BTW zero problems getting a lower 1/3 cowitness with an RMR.
