Why? Because every State that passes the law sees an immediate drop in violent crime. Criminals don't like the idea of their potential victims being armed.
Why? Because I travel alot and had two very young daughters. I maintain the license to this day. I only carry out of town. Although I was armed almost the entire time during WCBF as well.
I carry a Colt .45 M199A1 Compact (officers model size, 3.5" barrel). I carry 7+1 in it, and a single backup 7rd mag. Any more than that is purely ridiculous. The only original parts left on it are the frame and slide. All the rest were purchased aftermarket and hand-fit myself. Hours of custom work and tuning. Even the grips were made by me.
Very extensive mod list. Same one I nailed that Grouse with in that famous other pic.
