Just signed on today and I like my Kel-Tec pistols.
I have two Kel-Tec pistols. I first bought a P3AT after shooting a friend's and I've always liked it. Very small, light, easily concealed--lighter than my Beretta 21a and significantly more powerful. Also easier to conceal.
The second is a Pf-9 which I took an immediate liking to. It is not much harder to conceal than the .380 but it is a significantly more powerful cartridge. Unfortunately, the ejector pin moved and blocked the hammer from falling (while I was qualifying to add it to my CHL--annoyed, angry, etc.) Sent it back and they returned it in about 5 weeks. I am pretty sure it is a different pistol with the same serial number; I can't be certain as I only had it for about 6 days and 250 rounds before returning it, but I think a scratch is missing from the slide.
They both have brisk recoil, but I don't seem to mind recoil and I don't find them uncomfortable to shoot. Others may have a different opinion.
I find these 2 so much handier than my Kimber that I usually carry one of them even though I bought the CDP II as my primary carry pistol.
