It has always grated on me when actors in the movies chamber a round in their automatics for dramatic effect. No professional would ever carry a modern, high quality automatic without a round in the chamber. Every automatic I carry has a chambered round when I carry it.
With that said, many of the automatics, pocket and otherwise, made in the 1920s, 30s, and 40s, before this modern age of litigation, were, due to their design and the materials used in their construction, unsafe to carry with a round in the chamber. I still have a couple, that are in my safe for sentimental reasons, that belonged to my Grandfather. One of them is a striker fired Ortgies .32 that, due to a poorly designed striker and sear mechanism, could go full automatic in your pocket.
Just a thought on the subject.
