This is the best shooting 9MM I own or have ever fired. A CZ P09 I bought a couple years ago and really just don't get to shoot often enough (my every day carry is my CZ P07).
I took the plunge awhile back and ordered the RMR from some folks who kept saying they were going to start doing the machining work to install RMRs on CZs but so far just never got around to it.
I ran across some other folks, on another forum, that had posted some pictures of CZs they'd installed RMRs on, but with no rear back up sight. They were removing the rear sight and machining it out to open up the area for the RMR. CZ Custom was doing the same thing.
I want a back up sight. The RMR I bought isn't electronic (uses the daylight to light up the dot with fiber optics or a tritium source to light it up when there isn't enough daylight) but I still wanted back up on a carry gun (I don't do competition stuff).
Anyway, I shipped the gun of to an outfit called Primary Machine, and got it back a couple weeks later with the RMR installed, the taller sights installed (for back up) and the slide cerakoted in Magpul OD Green.
I hope to finally get to shoot it tomorrow.
