This is a standard, large-frame Smith & Wesson Volcanic Pistol. Firing a 41 caliber "Rocket-ball", only 500 or so of these pistols were made and they are rare and desirable. This one has the more common 8 inch barrel and is all-steel construction with an engraved frame. It is in a grey-brown patina with very good grips. The action is sluggish and the gun has an appearance as one that was found in a little bit of rough condition and then cleaned. This gun need a little TLC with oiling and grease to free up its action. I believe it to be moderately priced and a bargain for someone that doesn't want to spend $20,000 or so on a slightly better gun.
