You can make the greatest caliber ever, but it doesn't mean jack if the gun sucks.
.30 Super does seem to be oddly accurate and it holds more rounds, but that doesn't automatically make it better than 9mm even if it was available in all the same pistols that 9 is.
.32 ACP, if it's not in the pistols I want, I can't warm to it. I got the Zastava because it was cheap and didn't have a .32, I got the Beretta because I knew it was good quality for the price and if I'm going to be stuck buying a straight blowback pistol, I'd rather have it in .32 than .380. Kel Tec is the only one who seems to make a locked breech .32, so at the larger size if a .380 is available in a locked breech, I'd rather get that and will be this Summer when I get the Ruger Security 380.
.30SC, .32 ACP, .380 ACP... IMO, .32 NAA is better than all of them and it is unfortunately pushing daisies because the industry is terrible at marketing actual improvements. The industry is so disingenuous that it only knows how to market something that isn't an improvement. It's like a used car salesman who only knows how to sell bad cars to people that he doesn't know how to sell a good one when he ends up with one on his lot.
