Hand is die Hand in German
A pistol is a generic term for hand gun. The revolver is older than the semi-automatic magazine fed hand gun. Revolver hand guns came into widespread use in 1836 when Samuel Colt patented his first design. The first real use of semi-automatic hand guns was in the 1890s.
English "the hand" means German "die Hand".
If your revolver is an Iver Johnson Viking, it is a top break revolver. Holding the revolver in your right hand (finger OFF the trigger) use thumb and forefinger of left hand to grasp barrel latch (between back of cylinder and hammer) lift the latch, and revolver breaks open. If this does not work, take it to a gunsmith.
