He said plain clothes officers would watch someone as they neared a uniformed cop and they would change their stride and their "power" arm on the side they carried their gun, as if to shield or protect it....a totally involuntary move that is very very detectable to the trained eye.
Good to know info!
I carry a Glock 19 in a inside the pants holster in the small of my back. I do not keep a round chambered, for safety reasons.
I am aware that I am more confident when I am out walking, because of CCW. Therefore, I try not to issue a challenge to would be thugs by my behavior, by appearing overconfident. For this reason, I think I would be hard to spot.
Of course, I have a CCW permit.
Situational awareness cannot be overemphasized. I have headed off trouble several times by not letting questional persons get behind me, avoiding groups of thugs, etc.
