Your wife will never carry the P-12 ... it kicks like a mule on steroids and can't hit anything you would not be able to hit by throwing it. Its a lot better for a recoil junky than for anyone to carry these days; I'm a pretty strong handed shooter and I can't even hold back the muzzle flip with 2 hands, the mass of the slide is that great when it hits the end of travel. When it was made there was no competition in its class, that's why people bought it. If you doubt me, buy it and put it in her hand, I bet she will give it back to you without emptying the mag.
If you want the real collector's piece get a P-10 and the extended barrel (yeah, that's the top gun in my avatar). You still won't be able to hold it still, but at least you'll be able to hit a house a few feet away.
