Hello there, got a question for you guys. I have a model 19-5, 6 inch barrel, nickel plated that needs a new rear sight. I have seen several shopping around on the interent, but not really sure which is the correct one, and the correct sight height, if anybody could point me in the right direction that would be great. It has a fixed bead blasted looking front patridge sight if that helps any. I tried the Smith Smithing section but no replies. Thanks!
