I have a Model 19 S&W 6" have owned it for 30 yrs, the end of the barrel inside the frame next to the cylinder is split at 6 o'clock. Research on the internet says this happened from 125 gr bullets wich is what I was shooting at the time. S&W says it is unrepairable, don't have the old barrels in stock and don't make them anymore. I guess I need to buy a new/used barrel and find local gunsmith for installation. Love this Gun, don't want to give in to this problem. Hope somebody has ideas or suggestions, will be very thankfull for any help!
