If great grand-pappy was a Doughboy and shot a pistol, it was probably a .45. When our grandfathers and fathers were doing the business at Omaha Beach, Inchon or Khe Sanh, they loved having their trusty .45s handy. We civilians are still shooting the same round today, so if any pistol cartridge can claim to be America’s own, it’s got to be the .45 ACP.
Recently, several folks have asked why we cover the 9mm variations of Glocks/M&Ps and seem to ignore the other calibers, specifically the 45. So here are a random collection of thoughts on the Glock 21. When selecting a pistol for duty, it’s really hard not to get mired in a caliber debate. Without digressing too far, it is my strong belief that in service handgun calibers, using modern hollowpoint ammunition, the caliber used is of no real significance. Yes, you could split hairs, but for all intents and purposes handgun calibers are all weak.
