Also (and I know you didn't ask this, but just in case), if you are thinking about any of those for self protection. The 32 S&W (32 Short) and the 32 S&W Long are bad, bad choices. As a self-protection cartridge, they suck.
The 32 ACP, with the proper bullet choice (there is no good bullet choice in those other two) is marginally effective, but the "self-defense" 32 ACPs being made today - the Seecamp, the NAA, the Beretta - are all small and light, which helps for carrying, but makes them hard to shoot and recoil is increased.
The 32 WCF is obsolete. It's a fine cartridge, but finding guns for it, and more important, finding ammo for it, would be difficult.
The 32 H&R and the new 327 Federal are probably the best of the "self-defense" cartridges available in 32, but as with the ACP, the guns they come in are light, and therefore kick more.
