Hello Don.
 There are two possibilities. It is either a ..1894 First Model Safety Automatic Hammerless.., or an ..1895 First Model First Variation Safety Automatic Hammerless.. The difference is the 1894 model has a type of 'hook' on the top strap to hold the cylinder on the frame, which is activated by lifting up a notch to remove the cylinder, while the 1895 has a threaded bushing to hold the cylinder on the frame. These were called Safety Automatic's because they did not have a hammer mounted firing pin, like all other revolvers did at that time. Instead the firing pin was mounted inside the frame and was activated by a flat bar that raised to engage it, only when the hammer was fully cocked. This was so the revolver could not be fired by dropping it on the hammer. The Iver Johnson revolvers were known as the "only revolver you could hit the hammer with a hammer, and thus the safety was called the 'Hammer the Hammer' safety mechanism.
 It will not fire a .32 Automatic cartridge, since it was only designed to fire a .32 S&W cartridge loaded with black powder. Even modern cartridges in .32 S&W caliber are too powerful to be fired in this model. If you want to shoot your revolver, first have it checked by a certified, licensed gunsmith. If it is approved, just google for 'black powder cartridges' and you will find them for sale.
 I hope this helps answer your question, and thank you for asking for me. Charles Gage

I have been at the study of firearms and their use since my first issue of Field and Stream in 1962.At that time I was completely devoted to rifles, but over the years I have experienced the thrill of the hunt with handguns, shotguns and of course rifles. I moved from Oklahoma to New Mexico in 1972 and, since, I have taken numerous game and non-game animals with all firearms (cannons excluded)including blackpowder muzzleloading rifles,shotguns and handguns. My favorite handgun for large non-game animals, such as feral hogs, is my Uberti replica of a 1847 Colt Walker. Very heavy, but accurate.

I am a 1973 high school graduate. Junior and senior year I developed a class on Wildlife Depredation and Conservation of our Rocky Mountain states. My specialty was the brown bear.
