In 2015 when I put a Trijicon RMR RM07 on my M&P40 PC Ported I shared a picture of it on this forum.
The roar of the disdain and ridicule, scourn, and, laughter from the "experts" who had NEVER actually shot a RMR equipped pistol was deafening.
However, since I recognized the "experts" were actually on "experts' in their own minds and since none of them had contributed a cent to my purchases it mean absolutely nothing to me.
Now almost eight years later there's not a major single manufacturer that doesn't offer cut slides or even completed RMR equipped pistols.
As the original M&P OR pistols came with metal plates I've never had an issue as some apparently have with plastic plates.
I really can't understand why S&W did that.
Anyway, almost 8 years later and with thousands of rounds through RMR equipped pistols I'm more convinced than I was in 2015 that it was a great move FOR ME.
If the OP can shoot a RMR equipped pistol it would be a great aid in determining if he liked it or not.
All three of my Trijicon RMR equipped pistols have suppressor height sights and the dot just sits on top of the sights.
For me that made the transition far easier and I never really had an issue in finding the dot quickly, just go for a sight picture and the dot is there.
One thing I've heard some new RMR shooters struggle with is that after they find the dot then they try to make sure it's setting on the front sight.
That's unnecessary and slows down the shot time.
Once you see the dot ANYWHERE in the window get on your desired POI and break the shot.
Again, if you see the dot on the target you're good to go REGARDLESS of where the dot is in the window.
