That gun can come stay in my house any time.
Why the constant complaint about sleeved barrels? Until Teagule came around that was the only way to save old guns if you wanted to shoot them. I know that there are crude jobs out there but a well done one does not bother me in the least. Yes the loss of the damacus pattern is sad but at least the gun still can be used.
You have a gun no longer safe to shoot. Thin barrels are often the problem and when they get thin the loose weight. So the pre sleeved weight is not real or original anyway. It has been honed too thin and the weight has been reduced in the process. Every .010 is two ounces in weight. So if the barrels started out 3 pounds and walls of .035 but ended up 2 pounds 11-12 ounces with barrels with .020 walls the gun has often been rebalanced to a lighter weight if it still balances on the hinge pin. Your fast light gun is not what it started out as. You just fell in love with the thin walled, worn out gun that it became over time.
A good sleeve job may increase the gun by three to four ounces over the original weight. That can be rebalanced if you need it done. I find a gun that is three or four ounces barrel heavy to be very fine for my style of shooting. But if you have to have a gun balanced on the hinge pin it will weigh six to eight ounces heavier than when it was worn out. Still much lighter than most American guns, even if it does weigh more than when you first saw it.
