If you check Cartridges of the World spec page, you will see that a .32 long and a .32 S & W are identical...bore, rim etc...the .32 Smith is slightly larger in case diameter...run a chamber reamer to size for the .32 S & W, change the firing pin to central fire ....ammo available everywhere...or reload your own....I've done several like this...makes a sweet little gun with no ammo shortage....
