The Sheriff is a .22 caliber single-action revolver. Built on the frame of the popular Earl, the Sheriff has a slightly shorter 2.5" barrel. The most characteristic trait of the Sheriff is the rectangular shaped cylinder pin, which lines perfectly and compliments the octagonal barrel. This model comes with a .22 Long Rifle conversion cylinder which is a special longer .22 Long Rifle cylinder that will fit in the .22 Magnum frame.
