I was thinking of shooting one at a time and marking the case in the magazine to see top bottom or side to side , may be nothing , will have to measure how far off from from what area .. Once you mentioned lock up I can see now how fitting the barrel come into play . At this point I don't think it could be corrected without causing other problems . It's shooting 100% Just ordered CT Laser grips , have them on a carry Colt New Agent , just adds alittle fun in practice . Thanks for taking the time in answering my post . Be Safe out there .
PS
It is hitting alittle low at 6 o'clock , I guess I could use a unprimed case , remove the firing pin , look through the tunnel with the unprimed case in the chamber . Firing pin hole and flash hole should line up in a perfect world ..
