If you get on the kel-tec website there is a link on the bottom for holsters. That will give you plenty of options and most of them are quite affordable. I was looking at the fobus paddle holster.

I also really like the belt clips. You can get one from kel-tec that attaches on the takedown pins. The option I got was a universal clipdraw that attaches securely with double sided tape and can be easily adjusted for depth of carry. If you get the clipdraw it is easily removed for holster use.
