After shooting my Colt 1991A1 today I was happily cleaning and oiling my newest 1911 and I found that the plunger tube is loose. The gun doesn't even have a thousand rounds through it yet. Is there anything I can do with this short of buying a staking tool or taking it to a smith? If anything I would prefer to get a tool from Brownells and do it myself. I can always hang on to the tool since I have several other 1911's. Wanna kill these ads? We can help!
