Revolvers today? Pretty much the same old, same old—unless you’re rocking a Chiappa Rhino, you’re not turning heads with your wheel gun’s looks or mechanics. But rewind to the 1800s, and it was the Wild West of design. Innovators were throwing everything at the wall to see what stuck, and Ebanezer Starr hit the jackpot with his 1858 revolver. This bad boy was one of the first double-action handguns to swagger onto the scene, especially here in the good ol’ U.S. of A. So, next time you’re spinning your cylinder, tip your hat to the pioneers who made your six-shooter a bit more interesting.
