Whinging Poms!
For you Whinging Poms that have nothing else to worry about except what kind of pistol bullet the USCG uses....consider this fact. They also use Barrett .50 caliber rifles too. Along with Browning M-2 .50 Caliber machine guns, and five inch guns on Cutters. I would also assume their boarding parties carry automatic weapons and knives along with Stun Grenades and Frags. Horrors yet....they may even carry 12 Gauge Shotguns with Buckshot or Flechette rounds.
When was the last time the Geneva Convention really mattered to the Terrorists and Drug Smugglers out there? Ever watch a video of a terrorist beheading a hostage?
They can also call in Air Force and Navy attack aircraft if need be....what's a pistol bullet compared to a 2,000 pound JDAM?
Get a life guys!
