The fit is great. Nice and tight but still just right for a smoth draw. The only thing to note is that you need to flip the muzzel platform or cut some out of it to clear the rail on the M&P.
It fits tight and snug. I ran up and down the stairs, jumped up and down, and ran around with the holster unlocked and locked to see if it would fall out or wiggle lose. I plan to use it in my first match this weekend so we will see how it does.
Hope this helps some one else out.
I see 1911 CR Speed holsters in the for sale section alot for around $100.
