Beretta has also released a set of torture test videos demonstrating their own testing methods applied to one of the testing standards, I think, if anyone is interested. They cover water, sand, mud, and cold, I think, IIRC. That can give an idea of what Beretta had in mind when they were designing the pistol, most likely.
