It seems the internet problem du jour for the Colt 1911 is an off center recoil plug hole. Many owners are suddenly discovering this problem on their Colts that they never saw before. Many are sending their pistols in to Hartford for repair or replacement. Colt has a representative, Mark, on the 1911 Forum who is responding to the problem
I have not yet checked my Colts. I am almost afraid to. I've never had to send a gun back. I suppose I'll take a look this afternoon. Call me an ignorant old fart blinded by prancing ponyshit, but I still prefer Colts.
