Nice article from Ayoob, and a great reminder for the antis
"And, if you will, one more stark and simple thing: Americans have historically modeled their choices of home protection and personal defense handguns on what the cops carried. When the police carried .38 revolvers as a rule, the .38 caliber revolver was the single most popular choice among armed citizens. In the 1980s and into the 1990s, cops switched en masse to semiautomatic pistols. So did the gun-buying public. Today, the most popular handgun among police seems to be the 16-shot, .40 caliber Glock semiautomatic. Not surprisingly, the general public has gone to pistols bracketing that caliber in power (9mm, .40, .45) with similar enthusiasm. The American police establishment has also largely switched from the 12 gauge shotgun which was also the traditional American home defense weapon, to the AR15 patrol rifle with 30-round magazine…and, not surprisingly, the law-abiding citizenry has followed suit there, too.
The reasoning is strikingly clear. The cops are the experts on the current criminal trends. If they have determined that a “high capacity” semiautomatic pistol and a .223 semiautomatic rifle with 30-round magazines are the best firearms for them to use to protect people like me and my family, they are obviously the best things for us to use to protect ourselves and our families.
