Stepping It Up To .45
Next up is the Springfield Armory XD .45 ACP, a semi-automatic, double-action pistol that fires an 11.43 x 23mm Automatic Colt Pistol cartridge. This particular model is a compact with a four-inch barrel, suiting it well as a concealed carry.
Naturally, there’s a lot of controversy surrounding concealed weapons. But for the law enforcement officers and private citizens licensed to carry them, the internal struggle is over which caliber to carry. When size matters most, the consensus in most law enforcements forums is that a .380 is the minimum. But when it comes to stopping power (or heatspreader-destroying power), a .45 is the way to go.
