I have been carrying a Glock with a RMR 06 as a duty gun for just over a year. I don’t see myself going back to irons anytime soon. The things I had to work thru were keeping my presentation clean so the dot would be there and realizing that the dot appeared to wobble more at distance. Accuracy at distance now comes easy and fast. I’ve got a M&P 2.0 waiting to get milled for a Delta Point next.
