Good optic, plate fit was excellent - ADE Advanced Optics RD3-015 PRO Shake Awake 1x Reflex Red Dot w/SAR9 Optic Mount Plate

The plate fit better than I expected. No wobble and everything lined up correctly. Once I got the optic zeroed, it stayed put through my first several range sessions.

My only complaint is that a dovetail adapter naturally puts the optic a little higher than a factory optics-ready slide. It took me a couple trips to get used to finding the dot quickly.

Other than that, I'm very satisfied.
