Do any of you know what the Federal Air Marshal (FAM) program uses for guns and ammo on airliners? I heard once they were using ammo like the Glaser Safety Slugs either the Blue full of #12 shot or the Silver full of #6 shot. Other times I heard reports they were using either 9mm hollow points or 357 hollow points. Also do the pilots arm themselves too and with what? Common sense should tell you that even a 9mm or even a 38 Special HP has the chance to over penetrate in those close quarters of a plane and hit another passenger or go through a window or through the hull and cause a lot of problems.
