I have a question regarding the replacement of the medallions on Python grips. I've been watching ebay and there are constantly available "new" gold, Python Medallions for not a lot of money. Question is, should I decide to replace the medallions on a set of grips, how difficult is it? Is this something that has to be done by a professional gunsmith or can I tackle it myself? Appreciate the feedback from you guys....I'm a new Colt owner and this forum has been super!!!
