I used to have a P32, and shot a P3AT(.380) side-by-side on several shoots.
That little .32 surprised me on a few occasions during "ballistics-testing"haha. The .32 would do the job with several quick, well placed shots. Even one well placed shot. But, the 'well placement' could be tricky with any mouse-gun being the barrel length you're working with.
If either of the 2, .32 or .380, were my primary carry weapon. I would carry a spare mag or 2, and practice til the cows come home. Then keep practicing. And keep 'em well lubed always.
With strict, proper gun etiquette, you should never have to say, "It's okay. It's not loaded."
Be Safe! Teach Safety!
Take handle loosely.
