They used to be called drop guns in these parts. They were cheap handguns a policeman might use to cover his rear end to justify a shooting. They were never standard issue, just an extra gun, unregistered, someone could drop on a victim to justify a shooting. With the review processes in place now, and the risk of being video'ed at any given moment, drop guns have outlived their usefulness. For a civilian, or a policeman, to use a drop gun is just asking for jail time, imho. Lying in a criminal investigation is really bad news anymore.
