Hey, I'm glad I'm not the only one.
THis past summer I used some scrap wood and built a wooden strongbox for my pistols~ treasurechest sized. The leftmost quarter is reserved for ammo and miscellaneous. The right side has a botttom level and a top section that is a removable drawer. Top is hinged, front is latched, screws hidden. Simple but it fits the bill. Unfortunately, it leaves room for more pistols so now I have to get more...
