Again, your a typical American, you missed the point. The officers had .40S&W not the 10mm Auto; The 10mm Auto is a more powerful cartridge producing 588ft-lbs at the muzzle depending on load. The .40 is a weaker firearm. You someone twilight zone connected the .40S&W with the 10mm Auto. So your Point is terrible. The point I made was if .40S&W works, 10mm will work better.
