Hello there. I am looking at my bull barrel model 64 and although the barrel shoots straight it is alas 1/4" too short for me to keep it this way and stay in the good graces of the Law of the land. I have been looking at all sources of replacement barrels from 38S&W 5" to 6" full lug model 14 barrels. I can get by with just 4.25" which some of the new Smiths are Brownells has some PPC barrels made by Douglas that look pretty sweet. Then I read about folks using Colt Python barrels as well so any ideas or feed back would be appreciated. Local Smiths in my area with barrels to fit would say it will cost me $3-400 to do I nice job. Thank you.
