CorBon DPX. Test reports show the stuff functioning properly through leather and jean materials. Excellent petal formation and no plugging. I can't find a local retailer so I just order it from Midway or wherever may be cheapest online.
As for your 3AT, spend some time over at KTOG.org. Those guys are great resources for everything Kel-Tec. Find the instructions for the "fluff and buff" over there as I'm a believer that this ought to be done to every Keltec just to make sure no rough edges or tooling marks cause problems. Too many people don't spend a little time on the front end when they get the gun, and then complain about FTFs, etc. later. It's probably true that every brand of gun could use a little polishing of certain internals here and there (e.g., even our M&P's suffer from some rough edges that cause gritty triggers and squishy resets), but that goes without saying on a Keltec. The company admits it doesn't "fluff and buff" them before they go out the door, but that's o.k. when you're only paying $259 for a base model. One more thing, get yourself an Uncle Mike's slip-on grip in the small size for more control. Those DPX rounds have some snap. Also, I find the Uncle Mikes Size 1 pocket holster to be perfect. If you open the little extra sewed-up flap on those holsters, you can carry your 3AT and an extra magazine in the same pocket with ease.
