Have my mother's revolver, its an almost 20 year old Taurus 22 Magnum. Took outside plate off to thoroughly clean, have done it to other revolvers in the past. It had a gritty trigger pull before I took apart. After the plate was removed, had one loose part just hanging out. no idea where it goes. Thinking I need somebody a little more knowledgeable on revolvers. Cylinder is now free spinning and won't lock up. Anybody in Northwest GA can help? Gunsmiths? I can pay. My mother has a loaner pistol from me while I have this poor little thing.
