In with several S&W revolvers I bought about ten years ago were two .32s in fine condition, perhaps unfired. I don't remember the model numbers but one had fixed sights, the other had an adjustable rear sight. I kept these guns long enough to work up some good cast loads using an RCBS mould that cast an 88 grain flat nose, sized to .314".
Our tastes are all different, but at the time I found the cartridge to be an incredibly puny round, far less useful than a .38 Special. The .32 is probably best as a cast bullet cartridge; couldn't imagine wasting time with a jacketed bullet due to the ballistic limitations.
I sold both revolvers at a gun show. If I found another such gun today in good shape at a decent price, however, I might buy it to shoot up the several boxes of handloads I have. I realize that justification is not a good one.
A friend gave me a partial box of factory Remington .32 S&W (the short one) he retrieved from a closet in his dad's home. These were probably manufactured in the 1930s, maybe 40s. I still have some cartridges left, but don't remember the bullet weight. I chronographed a few rounds and muzzle velocities were in the 500 fps range. I don't know what you could safely shoot these at other than cardboard without fear of the bullets bouncing back.
