We still have one P32, I gave the other one to my son.
(Wish I still had it.)
The P32 has all of the bugs out of it, and is very easy to shoot.
I consider them to be excellent, reliable guns.
My wife still has hers.
My P3AT is back in Florida right now. The take-down pin kept walking, even after they sent me a new one. There have been a lot of improvements since mine was made, and I wanted the upgrades.
The P3AT is definitely more difficult to shoot. Can be hard to hang on to, because of the recoil.
Around here, it's easier to find cheap .380 ammo. Individual boxes of .32 don't go on sale.
I did like the last-round-slide-lock on the P32. Wish they would add that to the P3AT.
I'm thinking the P32 would be more fun at the range, and not that much less potent as a self-defense round.
