Manufactured from 1879 to 1887, the Model 320 revolving rifle is one of the rarest Smith & Wesson firearms manufactured produced with a total production of 977. These firearms were serialized from 1 to 977. The Model 320 was manufactured in three barrel lengths of 16, 18, and 20 inches with twenty being the rarest length, only 224 were manufactured by Smith & Wesson. The 20 inch barrel has a globe front sight and two leaf folding rear sight. The top of the barrel rib is marked with the two-line address/patent dates. The matching serial number appears on the butt, cylinder, barrel and barrel latch. Blue finish with casehardened trigger guard and hammer. The barrel is fitted with a checkered hard rubber red mottled forearm with the Smith & Wesson monogram on the underside. The grips are matching with Smith & Wesson monograms in a circle at the tops. The stock is smooth walnut with blue finished attaching iron and a checkered hard rubber buttplate with Smith & Wesson monogram. A factory peep sight is mounted on the stock attaching hardware.

Very good. The revolving rifle retains 10% original blue finish in and around the protected areas with the balance a smooth brown patina. Traces of original case colors remain on the hammer and trigger guard. The forearm and grips are excellent showing limited minor handling marks with overall crisp checkering. The stock is with a few very minor handling marks on the wood and 50% original high polished blue finish remaining on the attaching hardware. Mechanically excellent.
