“Cotton Comes to Harlem” was a delightfully un-PC blaxploitation film of the 1970s. The movie’s heros are two African-American plainclothes detectives who do normal buddy-cop stuff in Harlem, trying to catch the drug dealers and stay alive in the process.
In one scene they are being disciplined, suspended if I remember correctly. Their boss tells them to turn in their badges and their weapons. The badges are handed over, and then comes the removal of a tabletop full of guns from their persons. The last gun is handed over after one detective turns around, a zipper is pulled, much struggling with hands in pants is seen from behind, and a tiny little derringer is dropped atop the pile.
That is the only concealed handgun method that makes less sense than this one.
