I recently attained a GA CCW and a Kahr PM9 for personal carry in Atlanta. After 400 rounds at the shooting range, my groupings were still about 8" at 10ft. I don't believe that being armed like that will make anyone safer, so my gun is currently unloaded and locked in my safe at home. What can I reasonably expect for accuracy with this firearm, given that I will not be able to shoot more than three times a month? Also, what level of marksmanship would be considered adequate by a reasonable person (and a jury) before I carry for defense in public? My apt is about 30' deep and I would think being able to hold a 6" grouping at that distance is sufficient, but I really have no perspective on that matter. What does Law Enforcement generally require of their officers for qualification?
