I first bought a P32 for my wife as she is somewhat recoil sensitive due to long time work related injuries in her hands. Though she shoots quite well with my Glock 19, she needed something smaller for her purse.
After buying one P32, I ended up buying another for myself.
Though I do like the .380, the .32 ACP has long been considered a tack driver in target pistols. The cartridge just seems to have better inherent accuracy compared to the .380 cartridge. As for stopping power, let's face it! At very close range it isn't going to make that much difference between .32 and .380. Shot placement is the important factor and having the extra round in the P32 is another!
If I need to carry something more and I'm still trying to stay compact, I'll carry the Glock 19. And if I want the max, with great stopping power and still have good concealment, I carry my Star PD in .45 ACP.
But, the P32 is still my choice for just everyday, knock-about concealed carry. It is highly controllable, has decent performance, and after firing hundreds of rounds through mine, it has proved to be extremely reliable!
