For a 32 auto or even a 380 auto I do believe the P-32 would be near the top of a long list. I've shot a friend's P-32 several times and I do admire the little thing but it's shortcomings compared to the P-11 and other like type pistols are still serious. The P-11 can be aimed as well as pointed, the P-32 can only be pointed as the sights don't permit accurate aiming. The 9mm luger is about 50% more effective than the 32 auto, this shortcoming is often justified by stating that a P-32 (or any mouse gun) is better than nothing, the same can be said for carrying a knife or screwdriver. The P-32 and Seecamps represent the extreme in small design, however the bottom line is the effectiveness of the cartridge it fires, not the convenience of concealed carry. Generally in the past the only valid argument for effective use of 32's and such is multiple hits and bullet placement (head , heart, ect.) I don't believe this argument can be applied with the P-32 or other low powered mouse guns at any distance beyond 10 feet or so. Yes you will hit the assailant but you probably won't stop him and at less than 10 feet and coming you are in a world of hurt. The 60% stoping power rating some 32 ammo is given sounds impressive but for my own self protection at 10 feet or less I want as close to 100% stopping power as possible. I will compromise at 90% stopping power for the P-11, no less.
