I have a Python that I acquired second hand. This gun shoots quite well but I think it has had a fair amount of use.

I do, however, have to keep the firing pin spotlessly clean or I start getting missfires but I am also suspicious of the hammer spring and do not know if someone has fiddled with it in the past.

What I want to know is whether there is a spring tune-up kit available for the Python, from someone like Wolff.

That's going to be tough to get an un-altered V-spring for the Colt Python. You might try Ron Power's site, I think Power Custom or something like that. You could also try Brownell's since they have pistol and revolver parts. Of course, if you're lucky, you might even get a V-spring from Colt.

Natchez used to carry the Trapper spring kit for the Python, but it's not listed anymore. You might try contacting Trapper.

You may also want to watch the grip screws . On some style grips if the screws are to tight the trigger spring will rub the side of the grip causing the round not to go off . This happened on my Anaconda. I bought a heavier spring before I figured out what was happening.
I just keep the grip screws just tight enough so the grips dont move.

Thanks for the info guys.

I have located a trapper kit and have ordered it today, so we'll see what that does.

Also, I will keep an eye on the grip screws, too.
