Will try to make a long story short. I purchased a M&P 40, the first polymer frame pistol I ever owned. I have 6 Smith Revolvers, some are 30 years old and function perfectly. This M&P was a lemon! It jammed from day one, never functioned properly. was told to clean and oil it good as it could have dried out on display at the store. Had my gunsmith go through it, clean and oil it and for about 2 magazines it worked. This is with FACTORY ammo! Finally when my grandson was firing it, the damn thing blew up in his face, the slide flew back and hit a friend of his in the forehead cutting him, and parts went everywhere. He picked everything up, brought it home and accused me of trying to kill him! I sent the gun to Smith & Wesson, and after about 7 weeks I called and spoke to a customer rep. I am supposedly receiving a letter, but haven't as of yet. He said the frame was cracked, but the metallurgy lab determined it was not the pistols fault, but the ammo or a possible misfire jam.(??) They would replace it for $531!! After I got through cursing, I asked him to return my pistol but since it was damaged they could not. I told him I would take that $531 and put a down payment on another Kimber, but I would not have nearly $1300 in a piece of **** Smith. But, apparently I am out $750 and have no pistol. Last one for me and as far as I'm concerned, piss poor service. Happy Holiday
