Yes. I still love my 1911's dearly, but that M&P .40 is a hard piece to beat.
Ergonomics are excellent, reliable, 16rds of .40 S&W at your call.
Do the math:
M&P, 2 spare mags = 46rds
1911, 2 spare mags = 25rds (utilizing 8rder's, carrying cocked and locked)
I did a scientific comparison shortly after I bought my first M&P:
M&P .40, full mag = 2.2lbs
LW Commander, full mag = 2.0lbs
Stainless Gov't Model, full mag = 2.8lbs
Series 70 Gov't Model, full mag = 3.0lbs
Yeah, I hated to relegate my 1911's to part-time service, but the math doesn't lie. In fact, I liked the .40 so much I have since picked up an M&P .45 full size (10rds) and M&P 9 (18rds). You know what? They all feel the same, handle the same, shoot the same, AND offer S&W reliability and quality.
