I just bought a S&W M&P Shield 9mm... Took it to the range and after about 30 rounds, it started jamming horribly, capturing rounds, FTF,FTE.. about 4 times in each mag... Unusable.. Now, to be fair, I did not lube the gun , I took it to the range figuring there was at least some assembly lube in it, so I could try it out, run a few rounds through.. WRONG!.. I was shocked at the HORRID performance after only a few mags in a brand new gun, so I took it apart... This gun was shipped from the factory, stored, sold ,whatever, with NO lubricant at all.. Nothing. Bone dry, no grease, cosmoline, NOTHING.. Powder dry ...Good thing it wasn't stored in a damp environment or it would have friggin rusted.. Yes I know, MY fault because I didn't disassemble a brand new gun to make sure it was lubed before shipping, but really should I have to??.. the striker/firing pin assembly was sticking horribly, and the metal to metal contact zones were all galled with wear starting already with just over half a small box of UMC 9mm through the weapon.. It took me an hour to get the gun down to where I could get the striker/pin,spring assembly out and moving without sticking.. I am hoping it will be ok now that there is a little bit of synthetic oil on the contact surfaces, and the firing pin and spring actually move freely without GRINDING.. S&W really should be ashamed, thats all I can say... bob
