I had anew Glock G19 with CTC lasergrips- after 30rds I got rid of it. Had an untouched M&P40c - loved it! Had a custom M&P9c that I literally just sold 3 days ago - loved it! I'll probably never get rid of my M&P45 as I am just way too damn fond of it. Not one of my M&P's has ever had any issues what-so-ever. All work on the 9c and 45 was done by Dan Burwell of burwellgunsmithing.com. A true artists with M&P's and 1911's. The following is my M&P45 and 9c he worked on:

There's not a single pistol out there that I've shot that I'd rather have over one of these M&P's. By far the most accurate, reliable, comfortable, and down right fun guns I've ever shot/owned.
