When I was still working the job I inspected my gun and wiped it down at the end of every shift. It was no different than my squad car, ink pen, flashlight, etc. I went over everything to make sure it was working so my next shift or if called out I'm not needing to put gas in the squad, checked the oil, looked at my tires, my pen doesn't write, my flashlight needed batteries or charged. Same with my gun. Was it ready to go if I got called out.
We got paid every 2 weeks. When the paycheck arrived then my gun got stripped and cleaned. All parts were examined to make sure nothing broken, cracked or needed replaced.
Now that I'm retired I've found I've slipped a bit. However, when taking it off for the day I still give my carry gun a once over and wipe down. A thorough cleaning about once a month.
It was no different than in the military. If your gear wasn't ready to go then you weren't ready to go.
If you're not ready to go then you aren't prepared when needed.
