I bought my M&P 40 when they first came out. I got the $50 discount plus 2 extra mags (4 mags total).
I absolutely love the feel of the gun. It was my first semi-auto pistol. The glock and XD felt like bricks compared to it. The XDm wasn't available at the time I purchased my M&P and even though I think the grip on that is a improvement from the XD (not to mention the high capacity mag), I am pretty sure I still would have settled on my M&P.
With that said, ahem... ahem... Mine misfires like a SOB! I was in the middle of a friendly competition and it misfired twice in one clip. I then tried to fire one of the rounds 3 times, then I put it in my friends XDm 40 and it went off first try. I wish this was isolated case but it happen to me over and over.
I am assuming I just got a bad egg. My brother in law has a .45 he uses for his duty weapon and he swears by it. My gun was one of the first batches that was made. It even has the old slide release that is hard to use with one hand and a serial number that is less than 4000. Anyways, I filled out a warranty form on S&W web site and received a shipping label within a day or two. I just mailed them my M&P and I requested the new slide release as well. I will have to report back when I get it back from them.
On a different topic. Has any got their hands on the new M&P 22lr?
I can not wait to buy one! Unfortunately no local suppliers have them in stock yet and I am too cheap to pay shipping and receiving fees.
