With the frame size and weight of a Single Action Army revolver, the M-1873 makes a great practice gun for Cowboy Action or an ideal carry gun for camping, hiking or fishing. The M-1873 loads from a side gate and at the half cock position just like a centerfire "Peacemaker", but is chambered for .22 LR or .22 magnum rounds. The hammer is made to traditional SAA appearance and feel. A key-operated, hammer block safety is standard on the left side of the recoil shield.
