I don't own any .32s, but my brother just recently got himself an SP101 in .327. It was pretty neat gun. I personally really want Ruger to bring back the GP100 in .327 Mag. That thing is like Sasquatch; I've seen pictures, heard stories, I've even met people who claim to have personal experience with one... but I've never seen one for myself. I'd buy one in a heartbeat if they brought it back (and made it available in California).
I didn't see any mention of the .32 NAA (.380 necked to a .32). It is supposed to be a pretty hot little round. Hornady advertises their 80 gr. FTX to be doing 1000 fps at the muzzle. That is pretty nice, but I guess a little superfluous, considering light-for-caliber (~80 gr.) .380 Auto will be doing about the same velocity.
I also haven't seen any mention of the 7.92x24mm VBR (.30 Carbine cut down with a .312" bullet). The VBR Round was designed to fit in the Glock 17, and I believe it had a magazine capacity of 19 for a G17-length mag. If it could fit in a Glock 17, it could fit in pretty much any 9mm platform. I would love to see a similar .32 round that is designed for use in .45 platform handguns; a .30 Carbine cut down and loaded with a .312" bullet.
Another fun thing to see would be something like the .30 Luger, but as a .32. Maybe take a stock of old 9x21 IWI brass and neck it down to a .32. I'll bet that would be pretty fun. You could probably get some decent velocity on it, though probably not .327 Mag levels. For that, maybe having a 9x23 Win necked down to a .32 could do the trick, or maybe just a slightly expanded 7.62x25mm Tok. Either way, that little .32 would be sizzling. And, so long as the OAL was around the .45 ACP length, you'd have a huge supply of platforms to shoot it out of!
When I think of all the possibilities for a .32, I really tend to think it is an under-used caliber in full-sized handguns.
Oh well. Thanks for the post! I hope to join your club some day!
