The Glock 26 is extremely versatile. With a Pearce finger rest, it makes a fine belt/IWB gun. Replace the mag with a standard (flat floorplate) one and it works as a pocket (in cargo shorts/pants) or ankle gun. Replace the mag with a full-cap from a Glock 17 and it becomes a good home defense gun.
The little P3AT is strictly a pocket or exercise gun. When I am dressed in a suit or other constricting clothing, I wear it in a front pocket holster. I can also clip it to the elastic waistband of my running shorts when I exercise (and it's light enough that they don't fall down!).
If I could have only one defense pistol, it would be the Glock 26, no question about it. It can do almost anything I need it to do, while the Kel-Tec is more of a specialized "niche" carry gun.
I used to have a J-frame S&W revolver that served as a pocket gun for over a decade. I ditched it because I shoot the 11-round Glock way better than the J-frame, and the Kel-Tec is smaller and lighter, functioning better as a "deep concealment" piece. The J-frames don't particularly lend themselves to really fast and accurate shooting at speed, at least in my hands.
