I'm not a Kel-Tec owner yet, but have seen plenty that I would like to have.
I am thinking about the PF9 or P3AT for an everyday pocket carry. I've got to have something smaller and lighter than my Xd.
Also like the P17 just for fun and teaching my grandkids.
I have both of those plus the P32. All work well for pocket carry. I tend to carry the P3AT or the P32 in the summer when I'm in shorts but the PF9 works well for pocket carry also. If you're going for small & light as your main concern get the P3AT but if you want a little more fire power & not much bigger & one that's easier to shoot go PF9. I have the DeSantis Super Fly pocket holster one size for the P32 or P3AT & another one for the PF9 which are perfect for pocket carry. It's a tough call but they will sell you both if you're like me & just can't decide.
