Loading and manipulating a semiauto is considerably more complex than doing the same with a revolver. I’ve seen folks who were OK with a revolver, but were dangerous klutzes with a semiauto in their hands...
I'm not aware of too many attacks which occurs under a shed roof shooting some fair distance across a grass field at your leisure. Yet this that does not occur, under peculiarly simple and non realistic conditions is considered quality.
But, it's what I expect out of government people
Aside from the problem of "limp wristing" a semi-auto, the semi-auto is easier to load. Especially for a reload. Unless your revolver support moon clips for quick eject/load, you can do it much faster with an semi-auto magazine. Frankly, it's BS.
