We focus on penetration.
.32 more reliable, and at the level we're talking about, the small (but definite) power increase over .22 LR is important.
Erik, I'm feeling a little chubby, as I'm up to 150 lbs. Even my P-11 is too hard to conceal under indoor clothes in GA. Would I prefer more? Oh, yes. If I could, I'd go everywhere with a Taurus Titanium .41 Mag, or a Ruger 4 5/8" bl .45 Colt, or my Glock 24 on my hip. Unfortunately, that would mean losing my job, and facing harrassment, arrest, and potentially death. My P-32 fits into my pocket fairly nicely, OTOH.
Oleg, your pics are beautiful. Thanks again. I'm sure when you say shooting easily and fast, you mean at distance? I only practice rapid-fire at close range with my P-32, and I can fire each round faster than through all but one or two other platforms I own...
