1863 modifications were:
-In 1863, the 1858 had "Safety Slots" milled between chambers on the cylinder. The milled slot positively secured the hammer between chambers for safe carry by eliminating the risk of an accidental discharge if the gun was dropped or the hammer struck.
-had cylinder pin modification to prevent the pin from falling out during reload.
