When I read the response about a loaded gun I immediately thought the same thing. Glocks just don't go bad by no use.
LAPD and Portland Police Bureau had issues with failures to fire on Glocks when they went to them. The issue was traced to officer's oiling/lubing the firing pin channel
Anything is possible. I always cleaned my firearms immediately. I do not oil, I place a very small amount gun grease on the slid.
It is possible I had very little knowledge of Glocks. Kingsbury range was not a place to converse with the officer.
