Never try to diagnose why people who have to carry guns, but don't really want to will do what they do. I come from the world of Brake Cleaner and WD40 firearms "maintenance". Actually getting them to use Break Free....which we bought in mass quantity was hard. It is why I ALWAYS take LE gun issue reports with a grain of salt and like talking to people at the place with an issue first hand.
Heck, I did an OIS investigation involving an outside agency. I was amazed their Glock 21's even fired because the firing pin channels were stuffed with grease. After talking to the officers I found out that their "Rangemaster" who was a retired Vietnam era Marine, was using the hole on the bottom of the firing pin channel as a grease port and literally filling them with thick grease. I can only imagine him being he same guy complaining about them Glocks always having light primer strikes and failures to fire. A vast majority of the firearms world are in no way shape or form "our people".
