I just read
Pluckit's comment on another thread about the danger of forgetting you left a load in a gun. You sure don't want to do that!
I leave guns loaded all of the time, often for months at a time (always on a clean dry bore).
I have half a dozen 18" pieces of plastic surveyor's tape in my range box marked with a Sharpie, and tie one to the trigger guard of any loaded gun. Simple, easy and effective.
What do you do?
