I hope you like your P3AT as well as I do mine J Smith :) !! I love mine!!. I have about 150 flawless rounds through it so far. If you are looking for a holster for it, I would offer a couple of suggestions.
The P3 is really a pocket gun, but I generally prefer to carry IWB. The first picture here is a pocket holster from Ron Graham called the K-Rat. It can be found on this page.

Just recently I received an IWB holster from Kevin at K&D holsters.

I cannot say enough good things about this holster!! I like it a lot. Kevin also makes pocket holsters that are very nice. You have to wait a bit to get your holster from K&D Holsters, BUT, it is worth the wait. Kevin will work with you and make you anything that you want. He is a great guy to deal with!!
Here are some pics of the holster I got.
You won't see any pics of a holster looking just like mine on K&D's website right now. But like I said, if you are interested, just talk with Kevin, he will be sure to get you what you want!!
Have fun with your P3. It is an awesome little gun. A good site with lots of info should you need it for your P3 is,
