Well, Keith, I don't want to get into any religious arguments here, and that's all the "bigger hole is better" discussions end up being.
.380 ACP cartridge chambering seems to have something in common with .45 ACP, and that is a pressure ceiling that manufacturers just don't seem to want to exceed. That ends up with little attention being paid to improving the performance of factory loads. The .32 ACP is also originally a low pressure cartridge, but there are a plethora of "hotter" loads available seemingly because manufacturers seem willing to push the envelope.
If the .380 terminal ballistics ended up being midway between the hotter 9mm Luger and the hotter .32 ACP rounds, I'd be happy with them. But they're not. As I'm finding out, a hot .32 ACP load beats the snot out of a typical .380 load.
BTW, my P-11 fits in my jeans pocket just fine in a Kydex holster, but I greatly prefer a P-32/P-3AT sized pocket pistol because of their ease of draw. Even when wearing slacks with bigger pockets, I prefer the smaller pocket pistols because they're not so obtrusive even though the P-11 doesn't print. It's bulk is enough that I'm constantly aware of it. (Also, BTW, the Rohrbaugh R-9 is a full 9mm Luger in a package that's the same size as a P-32....)
I'm going to expand my investigation to compare the "Puncture Power" of a hot 9mm Luger round to a hot .32 ACP load from similarly short barreled mouse guns. My guess is that it will come out right where I wish the .380 would be -- between the optimal .32 ACP and the optimal 9mm Luger compact pistol (KT P-11, IMO). If so, the Rohrbaugh will be a winner as "what a .380 pocket pistol should be."
I've had two PPK .380s move through my safe, and they were equivalent to my P-32 in useful power and equivalent to my P-11 in size. IOW, all the disadvantages of a P-32 along with all the disadvantages of a P-11, but what I want is something closer to the power of a P-11 and the size of a P-32. Without comparing them side-by-side, it doesn't appear that the P-3AT or any other .380 is going to fill the bill. Simply put, that's why I'm excited about the Rohrbaugh. It smells like it will fit that bill....
