The Smith & Wesson Model 60 revolver is a 5-shot revolver that is chambered in either .38 Special or .357 Magnum calibers.
The Tanaka Model 60 is a 6mm BB version. A tiny little 5-shell revolver that doesn't feature actual shells. You have to load the BBs into the front of the cylinder as a gas reservoir inside the cylinder as well.
It's made out of ABS plastic as it is from Japan. It also comes with a BB loader.
Despite its low power, as an 6mm weapon its power ensures that if you are hit you are definitley going to feel it. It will only be effective over short range but it will still hit human sized targets quite easily and for this price its one of the reliable revolvers around.
