I have another WTH.... The supplied plastic mounting plates do not hold up to the 10mm 2.0, at all. Here's some more bad news, nobody makes a metal mounting plate for the Burris Fastfire. Burris actually list a metal mounting plate for the M&P 2.0 but it is concave on the bottom. Oh, how I hope someone proves me wrong but I could not find a metal mounting plate for the M&P 2.0 / Burris combo.

Another thing, the tall sights are great for bore sighting the RD. The bad, the tall sights make finding a holster a real challenge, the sights hang up on everything.

I really like Smith and Wesson. I own a few M&P's and a 629. The 10mm 2.0 has been a learning experience for me but I think it will work out in the end.

Oh, I had trouble with the back screw on the cover plate. I could tell it wanted to cross- thread, I got lucky. Good luck!
