I have a six inch Python that I got back in 1979 for a private security job. Years later I bulged the barrel and sent it to the Colt authorized service center (Bob's Gun & Tackle in Norfolk, VA). BAD CHOICE. They put a new barrel on it and reblued it. When I got it back the blue was black (what I called a S&W blue), the thumb latch was a rosy purple, the trigger action was horrendous. They hot blued the gun without taking it apart. The bluing that got inside screwed it completely up. Needless to say I retired the gun. Two years ago I sent the Python Back to the Colt factory. They reblued it the Colt Royal Blue and did some trigger work. The trigger is good but not as good as it used to be but diffenately better than when I sent it. I guess it has a lawyer's trigger now. Don't send yours to just anyone. Send it to a highly skilled and trusted specialist or the Colt factory. The price I paid was $165 plus shipping. My Python is still retired but will never be sold. I borrowed money from my Grandmother to get it and paid her back. It has a very special place in my collection and heart. I plan to pass it on to my step-son. This was also my first handgun and is the pride of my collection.
