A friend of mine has a Model 41 that the previous owner had scope mounted, removing the rear sight. He also has a couple of rear sights off of K frame revolvers that he mounted scopes on. He asked me if K frame sights will fit the model 41 and I don't have clue. He would like to know before he takes the scope off so he doesn't have to resight the scope if it doesn't work. Anybody know the answer? Thanks in advance for any help.
