Funny story about cleaning: My wife took "NRA Basic Pistol for Women" at the NRA HQ range in Fairfax. There were two instructors, I'll call them Betty and Sally. Betty was older and carried a 1911, Sally was in her 20's and carried a Glock. Both were practical pistol competitors. My wife got Betty as her instructor for the range portion.
My wife asked Betty how often a gun should be cleaned. Betty answered in a very gossipy tone, "Well, I clean my gun after every shooting. But Sally (eye roll) will go weeks without cleaning her Glock. It's sooooo gross!"
Back to the main discussion, though, I'm really upset that I keep hearing "A lot of cops are not into guns." To me, that is inexcusable. It's fine if they are not gun hobbyists, but the gun is the most prominent piece of gear they carry and the one we most intrust them to be responsible with. I don't want a surgeon who is "not into scalpels" or a carpenter who is "not into saws." It should be like the military was when I was in. Respect for your weapon was an absolute. You could get time in the brig for neglecting or abusing a weapon.
