Years ago the FBI in Miami gave some agents handguns and sent them to a rifle fight. The result was pretty bad. They could have admitted it was a dumb thing to do and improved their procedures but, being what they are, the Feds proceeded to spend lots of time and money on extensive studies which concluded, I guess predictably, that they needed to buy lots of new stuff. They needed handguns that held more ammo and went bang louder. Smaller agencies gleefully agreed. The whole thing is nonsense. Handguns stink even for personal defense, and are a joke for "combat". They're just easy to carry and conceal. If you've got to go where there might actually be some shooting at people, a shotgun or rifle is highly recommended. Better yet, stay home.
