I say this as someone with a Keltec P3AT: Buy one of the small single stack 9mm pistols. The best .380 load on the market only expands about 50% of the time, and IIRC, was tested through one of the larger .380 handguns...something along the lines of a Browning BDA. The 9 is cheaper to shoot, has a wider selection of good quality ammo, and some of the guns are only marginally larger than the P3AT/LCP.
If you're going to lean toward a wheelgun, I'd say just buy an airweight .38 Special and be done with it. The magnum version is, IMHO, a waste of money. I can't imagine one of them being at all comfortable to practice with using true .357 magnum loads(the 110 grain stuff is NOT full power), and I'm of the opinion that one should practice with what they carry.
