While I strive for a "complete assortment", I am not a "safe-queen collector." All mine are shooters.
Two or three live in holsters, are used, checked, oiled very regularly.
The rest, nearly a dozen, rest in foam hyscore "racks" in the safe. They too are oiled,wiped down regularly.
I keep a soft cloth lightly soaked in light gun oil in a quart jar right on a shelf beside the safe - always there in case of an emergency fingerprint!
