I probably have more "guns" (antiques, so not technically firearms by ATF standards) in 32 S&W, and 38 S&W than anything. Model 2 Smiths, Iver Johnsons, H&Rs, old police guns of various types (It seems 38 S&W was real popular with Alabama cops, alongside 32-20, until after WWII), all sorts of British and Belgian top-breaks. They are fun, but the cartridge is not particularly well adapted to most scenarios.
As a "get them off me gun" 32 might work.
I really like the period between 1875 and 1899, and it seems the models of revolvers with largest number of innovations and unique ideas (outside of early Autos) were made in those cartridges or in .500 Belgian.
I will share this story as half-remembered from a book I have on weird true stories of the Old West:
There was a marshal who carried a pair of Smith Model 2 (not to be confused with the Model 2 Army) revolvers in 32 S&W. Even by the standards of the late 1870s, the .32 was considered weak. The story goes that this marshal had really poor vision, and liked the smaller guns because they could be concealed until he could get close to his quarry, identify them, and guarantee that he could hit them. He pulled one of his pistols on a criminal in a bar in (I think) Nevada, and the guy supposedly looked at it and laughed at the little gun in the weak cartridge. The bad guy was still making fun of that gun when he pulled his own .45. That's when the marshal fired.
The little .32 entered the guy's heart, ricocheted off a rib, and exited the man's body via his butt-hole before lodging in the floor. This book, published in the early '60s, had a picture where the bar had preserved that chunk of floor, and was still in business at that time.
