I sent it into Colt to have it repaired and put back into factory condition and make it safe to shoot.
Question:
When I get it back, I still have to decide if I am going to re-blue the gun or leave it as is. Will it effect the value? If I do get it re-finished, who should I get to do it? Send it back to Colt?
Is it worth the trouble? Should I just keep it as a plinker?
Thank you in advance for the thoughts.
