A couple of years ago, I purchased a Zev Open Glock. When I finally got the PF high enough for the comp to work, the recoil did a job on my arthritic hands and wrists. I didn't try shooting Open with minor PF, that would be foolish.
Now I need to decide which one of my Glocks, I'm putting the RMR on. Right now I shoot Production with either my G21, G30, or G41. I also have a G17 and G19, but really like the larger holes.
I'm looking forward to shooting this Division.
