What caliber is best for duty? #fypシ #pistol #9mm #40cal #45acp #duty #springfieldarmory
This video discusses the trade-offs between 9mm, .40 S&W, and .45 ACP for duty carry firearms. It highlights that .45 ACP offers significant energy due to its heavy, slow projectile but sacrifices capacity. 9mm, conversely, is faster and offers higher capacity but less energy. .40 S&W was presented as a compromise between the two.
