Smith & Wesson "Dummy" model 58 .41 magnum ( PR21775 )

Smith & Wesson "Dummy" model 58 .41 magnum caliber revolver. Rare! Looks and feels like the real thing but it's not. The cylinder can't open and the action doesn't function. Marked "Dummy" on the butt where the serial number should be. A rare and unusual Smith & Wesson training piece, in excellent condition.
