It comes down to what purpose a person is going do with the revolver. For me buying a Colt Python is strictly for investment. Buying a model 27 is for shooting 357 magnums all the time. That is where the Python falls short. A person will have to have the Python worked on if the revolver sees lots of 357 magnums. In my area I don't know of any gunsmiths that will work on a Colt. A lot of people will say shoot 38 specials in a Colt Python so it will last longer. I would say forget it. If I am only going to shoot 38 specials then I have a model 10 or several K frame magnums that will shoot unlimited amount of 38 specials.
Bottom line: For me it only makes sense to buy a Python for a investment.
