APB on the suspect “Small, gun metal black, holds several cartridges, safety lock, trigger... if seen do not approach, guns are armed and dangerous”
Interesting! Last night I watched an MGM short Souvenirs of Death (1948)

I remember lots of cop shows in the 1970s whose major theme was a man buys a handgun, gun escapes and goes on a killing spree till captured and melted down into a sewer cover.
