I had a Ke lTec P11 with a magazine extension. It was easily concealed and I could brute force it onto target, but I didn't care for it as compared to my PT609. I gave the P11 to my Dad for Father's Day.
I shot a Ruger LCP, if you want a great pocket pistol that is the way to go. Me, Im low budget with a PT22 on those days when I'm not wearing enough to reasonably carry anything else, and my PT 609 on most other days, unless I'm dressed to carry my Judge.
Make sure you shoot a Kel Tec before buying, its a handfull that will take some getting used to.
