Congrats on your new permit. Remember that the easiest way to spot most carriers is by them being nervous. Just try to act the same way you always have.
Between the two, yes the P3AT will ride easier in your pocket but I'd trust the 638 to do a better job stopping the attacker. A revolver will work pressed up against something/someone where as most auto's won't.
I think that your 638 should be a nice first carry gun. I wouldn't worry about using it for belt carry though, pocket carry is what is built for (not that it won't work, its just that you might as well have something easier to shoot and/or more powerful on your belt).
A P3AT would be a nice addition but I'd recommend it as a second gun for those hot sticky days. The 638 in one pocket and the P3AT in the other. Remember that you might have one hand occupied either carrying something or attempting to fend off your attacker. If your only gun is in your right pocket and your right hand is occupied you have a bit of a problem. Also, some find the recoil harsh.
One of the main advantages to pocket carry is that you can have a firing grip on your gun and no one is the wiser as its still in your pocket. That can be real comforting as you attempt to avoid the confrontation.
I would recommend something larger for a belt gun, probably a 357 as you already have the 38. A medium framed 3-4" barrel should work nicely. The main reason I recommend the revolver is that you already have one, its easier to only keep one caliber of ammo around. Yes, in case you didn't know, you can shoot 38 Specials through a 357 Magnum gun. The 357 started life as a slightly stretched (and much more powerful) 38. Plus you don't have to use the full power magnum loads. There is getting to be more medium loads out there. When I had my last 357 (it was a vehicle gun, securely stored) I loaded it with Win. 110gr JHP's as they were a medium velocity load and I was out of practice with the full power stuff. It would still out perform a 38 +P if I would have had to use it.
Now, if you wanted to go to a semi-auto for a belt gun I wouldn't argue.
