Worn finish usually indicates carry rather than excessively shot. Remove the rest of the hammer spur (it is useless as the proverbial mammary glands on a boar hog). A hammer spur on a S&W double action, especially a gun that is intended for defense, lacks logic. I would jump on that gun at that price and use it as a practice, and/or a carry gun. Unless it has been shot loose, it is not a "beater".Refinished, worn, timing is okay(not tight) barrel is clean no pit cylinder walls clean. Hammer is bubba'ed some about 50% of the lenght of a regular hammer.
$180 worth it for beater?
