I have one and really like, and 'appreciate' it. What I mean is that I am very aware of its limitations, tactically, and ballistically. Is it my FIRST choice in handguns for a fight? Nope. Is it a handgun I can drop into my pocket, have ready access to it, and even "make ready" without drawing attention? Yes.
On these type forums, you'll often hear discussions of 'backup guns, or bugs. I tend to regard my KT as simply one of the guns on me at the time. It may be the only gun on me, which defaults it to the primary for lack of 'competition'. But that is rare. Most often, its carried in conjunction with a larger pistol, ie Glock 36. However, I dont mean to say that the KT is now a backup gun. In fact, being NON leo, or security or anything even remotely like that, chances are that if a situation devolves to the point guns come into play, I have probably already put my hand in my pocket and accessed to Kt, and will use it to fight back to cover & concealment to draw and fight with the larger gun, should things continue to escalate.
I hope I havent muddied the water of your original post, and I hope this helps.
