hello everyone, first time on the site for me. I received a S&W model 29-2 in .41 magnum after my father passed. I've been trying to find information on this gun from day one. I keep coming up empty on all avenues. It has a serial number, and i have found that it was manufactured in 1977-78 but S&W cannot tell me if it left the factory as a .41 or as a .44. It is nickel with 8 3/8 barrel. Any info would be a great help. Thank You
