I watched it yesterday, as I subscribe to MAC. I was thinking about posting it here, too.

PS There has never been any doubt that most autos (speaking of those adopted by large departments and/or militaries) are far less vulnerable to mud and sand than revolvers. When folks said revolvers are more reliable, they meant those revolvers that are properly maintained, clean, etc., and from the draw. A properly functioning, clean, revolver, loaded with quality ammo, drawn from the holster and fired was, for a very long time in US history, more likely to get through the cylinder without a hitch than was an auto pistol likely to get through a full mag. With modern autos, however (post-1980), that's not the case. Modern autos (those adopted by large departments and/or militaries), under those conditions, are about the same as revolvers in that regard now.
