Remember the (infamous) FBI shootout, wherein a number of agents died and the end result was the agency adopting the 10 mm? Which became the .40 S&W (because some agents couldn’t handle 10 mm). Then some specialized units of the FBI adopted the 1911, in .45 ACP?
Well, it’s time for gun/ammo roulette once again, folks!
Because 9mm has been shown to be so effective in the street.
I see this as a combination of federal agencies employing physically smaller persons (some minorities, women) and those folks being unable to handle (or perhaps not being properly trained to handle) firearms in a major caliber.
Or, perhaps it’s just because they bought a boatload of 9mm…
