I was in Walmart, picking up some things, and at the checkout, a local LEO was wearing a nice button up shirt, khaki pants, etc. He was wearing a nice leather shoulder holster, Glock inside. My good friend and coworker are both gun guys, and I asked..." I know it is holstered, but is that guy muzzle sweeping us"? Again, I know it is holstered, but these things are mechanical pieces. Anything can happen. It was awkward getting swept every time the guy moved, so I popped over to the next self check out and 2 minutes later, I was checked out. Just an interesting thought. What are your thoughts?
