If directed at me, then yes. I would say night sights are pretty much ubiquitous these days in law enforcement. They were pretty much ubiquitous 20 years ago too.

Last issue was Trijicons I think. No vibrating loose issues to my knowledge. That said, most deputies under age 40yoa have tac lights semi-permanently mounted these days too, limiting the value of night sights somewhat. Dicks, jailers and an occasional old timer on days are the only folks with slick guns.

Regular deputy guns are cleaned annually or more often, usually in association with the annual in-service training days. That meant inspection, cleaning and reissue was a smartly performed process. My assumption was we did as part of accreditation/insurance risk management drivers more than it just being a good practice.

SWAT guns generally got dunked more often. Mostly ARs, but also 870s, MP5s and an old time Uzi on occasion.
