Perhaps you are referring to the never-ending you-tube "torture tests" of various guns. I don't put much stock in any of them. The worst torture 99% of CCW guns will ever see is a little sweat and a lot of over-cleaning. Many of those "tests" are not even repeatable with another gun of the same make and model. I watched one "test' where a 1911 would not fire under water and a Glock would then I watched another "test" where a Glock would not fire under water and a 1911 would. There's nothing controlled or scientific about these "tests". I suppose they do have entertainment value though.
