I have had my M&P40/357Sig for almost two years now and it is my Eveyday Carry Weapon with a Crimson Trace Laser Grip. I originally purchased the M&P in the 357Sig caliber and obtained a 40S&W barrel from(www.gunbarrelsupply.com) of which I have the 40S&W barrel installed as of right now loaded with Federal 165 grain HST JHP. The barrel change is a breeze and is just a matter of field stripping and replacing with the barrel of your choice (357Sig or 40S&W). When I shoot the 357Sig I normally load it with 125grain Speer GoldDots. I am ultimately satisfied with this weapon platform and would not sell it if someone offered me twice what I paid for it but that's just me.

i had a mp40c for a while. it never jammed, but the slide lock had a mind of it's own. i sent it in to s&w three times and they couldn't fix it. eventually sold it to fund another 1911 purchase. it's an issue that affects a small minority of them. i'd still recommend getting one if that's what you want. they're pretty accurate, and would feed anything.

A stock M&P doesn't interest me. They feel good in the hand, but the lack of distinctive trigger reset keeps me from being able to run them with any accurate speed.

I am interested in an M&P45 with one of the APEX trigger kits to be used solely for IDPA CDP, but I'll have to come across a great deal on such a pistol to get one.
