Not sure exactly what you'd like to know but....
The 1911 grip is a natural for me and the M&P nearly matches it plus there's the flexibility of different sized grip panels.
1911 trigger is better of course being a true single action but the M&P can be much improved by buying a replacement sear kit from Apex Tactical ->

M&P weights less (empty) than even my scandium SW1911 .
M&P has more capacity, 10 +1. Larger magwell makes reloads a bit quicker to those like me who aren't an expert.
M&P doesn't have a grip safety so there's no chance of that stopping the gun from firing in the case of a less than ideal grip, e.g. awkward position, injured hand, etc.
Neither gun causes any excess recoil for me but the polymer should, in theory, flex and absorb some of the thump.
Being polymer, the M&P allows the user to do his own stippling on the frame and grip insert for added traction by simply using a soldering iron.
Anyway, that's my two cent, for what it's worth.
