So far (only about 400 rounds) its worked flawless. I did have to trim the screws that were provided as they went too deep and started pushing the plate up (See photo). However, once I filed them down slightly there were no issues in the install. This may just be that I got the wrong screws, I did reference the instructions to verify I was using the right set.
The ledge that lets you rack the slide off the optic mount instead of the body is a cool addition. It does seem to keep shooting residue off the glass as well. Pretty nifty.
I cannot use my stock irons with this setup (Previously had an RMR mounted that I could), so I will need to change my sights a bit in order to have backup options. But thats sort of to be expected.
