I tried to like pocket carrying a 9mm that size and I just can't.
I feel the same: the "idea" of pocket carry, at least with most guns, is far more attractive than the reality of actually doing so. And doing so suggests that you think you're going to have more time available to get the gun ready to use than you may actually have...
A side note: I've had a number of Kel-Tecs over the years, and despite their reputation for being cantankerous, mine (P-11, P3AT, two Sub-2000s [9mm and .40] and a PF9)
have always been 100%. I "fluffed and buffed" the earliest ones, but didn't even bother with the PF9.
Years ago, I pocket-carried a P11. Then a Kel-Tec P3AT and later a Ruger LCP. I now carry a PF9, but in an IWB holster. And I'm thinking about switching to something a bit bigger (also IWB) that I shoot better and more comfortably, so that I'm sure the first shots will go where they should.
(With the Kel-Tecs I've owned, the first one or two shots -- arguable the most important -- often aren't where I expected them to be. This was less of an issue with the PF9 than with the P11. When you shoot at the range, you don't pay attention to this sort of thing... and after a few rounds, the guns do well. It's not a gun thing, either -- it's a "shooter" thing. I learned this big time when I used the P11 in an IDPA match. My first three shots were disappointing; the rest of the match I did very well with it.)
If you're in a restaurant and sitting, getting the gun out is very difficult. If you're driving (moving or stopped) getting the gun out is very difficult. Sometimes, just walking, getting the gun out can be both difficult AND TIME-CONSUMING.
Many -- perhaps most -- confrontations requiring that you be READY to use a firearm can come on you very quickly. Perhaps more quickly than the time available.
I've had a bunch of Kel-Tec guns; presently only a PF9 and the PMR-30. Most of them (never had the P32, but I hear good things about it) require a good bit of practice to develop proficiency, ESPECIALLY if you shoot other guns in the meantime. The PF9 has a more conventional trigger, but it is a beast to shoot; the P11 is a less "normal" trigger, but the gun is more pleasant to use.
I always used a well-made pocket holster with the P11, P3AT [and a Ruger LCP] and the PF9 (when I tried pocket carry with it.) ( With the PF9, I also used some grip material that noticeably reduces felt recoil; I don't mind practicing with it, now.
BE SURE you really want to pocket carry before you commit yourself to a gun and a method that may not work for you. (A small water gun in the pocket for a while might help you determine whether it'll work for you.)
A recent Guns & Ammo (the latest) has an extended test of 10 different small, polymer "almost pocket guns" and the PF9 is one of them, along with all of the newest iterations of various other pistols, including the Glock. (The P11 isn't among them, however. You ought to pick up that article and read it to see how the various guns perform.
Five different shooters (two staff members and three long-term LEOs) put 650 rounds through EACH of the guns tested in rotations so that the performance was representative of all shooters.. The articles provides detail and summaries of the problems encountered and gun accuracy. One of the shooters (a staff member of the mag) seemed to get the best out of each gun... and the accuracy of one or two of them was amazing. The rest were about what you'd expect. (He shot a couple of sub-2" groups with a couple of the guns, the smallest from the Taurus PT709 "Slim". That got me thinking!
