I am getting ready to refinish my blued colt python. I talked to Colt customer service and they recommend Custom Shop Inc. in Montana. I also heard that Baron Technologies and Turnbull do a good job. I am trying to get the same Colt Royal Blue finish back on the revolver. Colt says Custom Shop Inc. is very close the the original Colt Royal Blue finish. Does anyone have any experience with any of these companies and who is the best one for the job?
