The KelTec is difficult because it is tiny. So, you are literally “trying” to hold onto it. It has a bizarrely long trigger pull, and a somewhat narrow trigger. You are also trying to avoid “Walther bite” on the top. Meanwhile, the weapon itself has no weight to it – so all of the energy is transferred directly to your hand. As mine was one of the “problem” guns, I had to keep taking it to the range and firing a hundred or more rounds at a time through it. It was literally load-the-magazine, empty-the-magazine, load-the-magazine, empty-the-magazine -- over and over. I didn’t even care where it hit – as long as it went bang.
I wouldn’t recommend it to anyone for a plinker. And for self-defense, its best application is when the baddie is close enough to punch, but you don’t feel like scrapin’ up your knuckles.
