OK I just bought the M&P 22 for my GF and this thing is brand new and it has jammed so many times now it's not even funny. It doesn't like American Eagle .22 LR ammo. It doesn't like CCI .22 Quiet 22 either. The only ammo that it seemed to like was Remington 22 LR Thunderbolt. The lady at the gunshop told me to do a full cleaning on it because sometimes they come with way to much grease from the factory so I took it home and disassembled it and did a full cleaning. Sprayed that sucker with cleaner/lubricant. Left it on for about 1 hour and wiped it all out. Lots of dirt indeed. I am hoping this fixes the problem because I am starting to really get upset. New gun and it wasn't cheap either. Any suggestions? All comments and inputs welcome.
