Good luck with the M&P, I have no experience with them, but while at Guns and Leather I saw an XD fail when 2 guys rented it it was a 40 cal and the firing pin broke,(they replaced it with a Glock) it was the first time I had heard of one failing, a month later the firing pin broke on my XD 45, after less than 500 rounds had been fired through it, the gun was bought by me New, as well as a Tactical model XD that I never shot, I sold both guns and replaced them with Glocks I know that Springfield would stand behind these guns but I lost all faith in their reliability when I saw this happen to somebody else's gun, then it happened to me. I now own 3 Glocks and I cannot seem to make them malfunction, for the money IMHO they are the Best pistols made for the price
