I've got five screw pre model 27 S&W 357 magnum that could certainly use the attention of a good gunsmith. i know the cylinder stop is worn and rear sight blade needs replaced. I don't want the well worn finish messed with i am only wanting to get this nice gun back in proper shooting shape. I took it to the range and even with the bad rear sight it could be a great shooter with a slight amount of work. So come on folks lets hear some options. I do have a cylinder stop and rear sight blade, waiting on a sight screw and nut currently.
