I carry the Keltec 3AT with a pocket clip in jeans, shorts, soccer/physical training pants, dress pants, and on and on. For the dress pants and PT pants, I do switch to an inside the waist band location given the less horizontal pant pockets. And I always carry a spare mag in the left pocket. I rigged my wife’s Ruger LCP with the same clip; works perfectly. Regarding unholstering and reholstering, as with any weapon rig set-up, definitely practice, practice, practice in as realistic scenarios as possible. I believe that most attacks are very fast and very violent- train under pressure and train like you expect to fight.
