years ago my at the time brother in law had just went thru cop school and had a job with a local town as a leo. he spent the evening tellin me how his glock was so much more powerfull than my 357 ruger revolver. i knew the boy and how full of sheet he was.
i said hey lets shoot sum guns. he popped off a couple of rounds with his 9mm glock,i shot it and it was nice, then i handed him my gp100 with full house loads. KABOOM!!!!!!!!!. he almost dropped it.
i said tell me now about the power of a 9mm ,he just looked at his shoes and said damm dude i had no idea!
