So I have a brand new ccp m2. After about 50 rounds in this thing starts to fail to go into battery. After a few more magazines the slide will lock up. It seems that the piston is expanding and getting stuck after it gets hot. I could be wrong on this but that is what it looked like to me. Does anyone have any ideas? I think i will actually try lubricating the piston and see if that helps at all. My wife has an original ccp that runs smooth as butter.
