My Zev OZ9 has the RMR mounted and zeroed for 20 yards. Before I mounted the RMR, shooting the pistol with the irons hit left between 1-2 inches.
I look at the rear sight, and it seems to be centered in its groove in the slide.
I'm sure others have run into this. I can move the rear with my sight pusher, but before I did, I wanted to find out what others may have seen with their pistols.
