This is a very nice all original Smith & Wesson 18-4 revolver chambered in 22lr. Mechanically this pistol works great and is an absolute pleasure to shoot.  This revolver has a 4″ barrel with an excellent bore.  The deep high polish blue in very good shape throughout.  The grips are high polish factory grips and are excellent all the way around.  The color case hardened parts are still in excellent condition.  Overall, this is a great example of a Smith & Wesson 18-4 revolver.
