Yes, even Wild Bill was carrying only a pocket pistol, a S&W .32 rimfire, when he was killed in Deadwood in 1876.
His eyesight was bad. It had been deteriorating for some time. His gunfight days were basically over. I’m sure the pistol was for personal protection.
BTW, he was born about 35 miles straight South of me in Troy Grove, IL. There’s really nothing left down there of the homestead, though I believe family descendants may still own some property. The Amtrak station in Mendota, just a few miles North of there, has an area museum affiliated with it that’s open on Sundays. It has a couple small books on the Hickock family during that time, and a Mendota connection. I’ve often thought of stopping by and getting them, but have yet to do so. Maybe Sunday...
