My worst experience was with a Kel-Tec P-11. First, the pistol is just fine in terms of size, ergonomics, sights and for use concealed carry. However, it had to go back to the factory twice to get it "right." Factory support was the best I have ever experienced; fast, inexpensive and very customer oriented. But by then I had lost confidence in the pistol. The final straw for me was the trigger. So long. The longest pull I have ever encountered and there is no remedy. I must admit that I would buy another if they would charge more for it and fix the quality control and trigger.
