This is the Smith and Wesson 642-2 Airweight in 38 SPL. This revolver has a set of Crimson Trace laser grips installed and a 1.87 inch barrel. It has a five round capacity for its 38spl ammunition. These guns come in at a dry weight unloaded of a very low 15.3 oz. It seems to lock tight as it should. These Smith and Wesson revolvers are very reliable and easy to carry firearms. This one is in very good clean condition and would be a great revolver for every day concealed carry.
