I am most familiar with Glocks, and carry a 21 (C-Tac IWB at 9:00).
I am starting to think of back-up pistols, and have seen mentions of Kahr, Kel-Tec, and Rohrbaugh on this forum. I am completely ignorant of this genre of minipistols.
If you care to weigh in on any of these (or others of which I am unaware), please do so. I am not looking for detailed specs, which I can find myself, but your general impressions of reliability if you have fired or carried any of these, recommendations for or against. etc. Thanks.
