Of course you could pull the .32, unload the magazice at the perp, and hope he laughs himself to death.
Home or personal defense demands stopping the agressor, NOW! One or more shots, center mass. A .32 is not suited to the task.
And please do not tell me of those lucky shots from a mouse gun that felled the 350lb, drug crazed nutcase. Sure it happens, but not enough to bet my life on.
I would never recommend a Kel-Tec P-32 for home defense, or for a first time gun buyer. I said it is an ideal concealed carry gun, and it is. The gun you have with you is a lot better than the one you don't. The Kel-Tec will sit unnoticed and practically unfelt in the front pocket of a pair of pants. I like my .45 auto, and it would be my first choice to have with me if the chips were down, but it isn't suited for concealed carry, unless I'm heavily clothed. A .32 will get the job done in a pinch. Your ridiculous comment that a perp would laugh himself to death if you emptied a .32 magazine into him is nothing but hyperbole.
