I realize this is a reloading forum but most everybody on here knows a great deal about guns. I think I repaired the rear sight on my model 29 44mag but if not I'm going to order one from brownells. They show that my gun will take a .160 inch or .126 inch rear sight. Does anyone know what they are referring to with the sizes? They don't list one for my gun by barrel length like they do some of the others. It is 8/38 long. Thanks in advance for any replies, FullCry
