I have a Kel Tec P3AT .380 caliber pocket pistol. I suppose it gets the job done but it was a total pain to shoot at the range because of the unavailability of .380 ammunition and the form of the gun (small size, big caliber = heavy recoil).
I decided that if I wanted a gun that I could feel comfortable saving my life with, I’d have to shoot it often, so I got the Glock 26 subcompact 9mm handgun. Not really a pocket pistol and a lot heavier than my P3AT, but still a small gun.
Couldn’t be happier. 9mm is incredibly inexpensive and prevalent, I can fit 10+1 rounds in it (expandable up to 33 rounds if I wanted to get ridiculous), and I shoot it every week.
But if you still want the pocket pistol, the P3AT is a decent gun.
