I laughed when reading his explanation of the 10mm:

"This round was designed for the FBI when the Bureau found the 9mm woefully inadequate."

Does he not know the truth or is he just repeating something he read on the internet?

Kind of reminds me of the people that ask me "Why did the FBI adopt the 10 mm first and then go to the .40 S&W later?"

BTW, I usually read his stuff when I come across it. I enjoy his sarcasm.
