By the mid-1880s the gun became the standard side arm for the army and was referred to as the Single - Action Army Revolver .Many civilian models have been superbly engraved and / or plated in precious metals over the revolver’s lifetime. The series presented here replicates some of the styles of decoration used on Western (4 inch barrel) and Cavalry (7 inch barrel) guns.
