If I discovered on of my friends keeping their firearm stored in such a jackassish way, I would not be able to hold back the flow of "stern education" that would fly from my mouth with great force and speed. I'm sure the officer frowned upon that as well, which is probably why your buddy got what he got. If everything was squared away in a respectful, responsible manner, things may have gone differently. Just my personal thoughts on the matter.
Yep that's got to be it, he was mad about the safety part of it, that's why he muzzle swept me..... Your handle may not be true.... I didn't come here for a lecture on holsters, just the actions of the officer and situation.
