I'd like to point out that in the hands of a Terrorist a simple box opener can bring down a skyscraper. It all has to do with the terrorist's murderous intent, and not, as the scare mongers try to make you believe, the weapon they are holding.
At the range we call such weapons "Lonely guy guns". Usually ported by a short guy with no friends who brings a 'cannon' to the range fires it a couple of times and suddenly he is surrounded by 'friends' checking out his 'big' gun.
Lonely guy guns ... not terrorist weapons.
Now, lets talk about the 50 caliber pistol ... ;)
