H&R "American Double Action" (DA only), nickel plated, 3" bbl, in .38 S&W caliber. The story goes my grandad carried it in France during WW I.
I think there is a discrepancy between the bullet diameters of the .38 S&W they were selling then and what you get now. The grooves and lands of the old gun's barrel are in perfect shape but nobody who shoots the old gun can hit within 6" of their aiming point at short ranges like 10 yds. However, it might have something to do with the triggle pull, feels like it's about 25 lbs.
It must have been alright for "gedda" (sp?- Czech for "grandpa"). He came back. Pretty interesting, him basically fighting against the country of his birth (Austro-Hungarian empire).
