Common pocket pistol calibers are .25acp(6.35x16mmSR), .22lr(5.6x15mmR), .32 acp(7.65x17mm), and sometimes .380 acp(9x17mm). All of which can be lethal, but very weak calibers in comparison to other pistol rounds.
BTW, for those that don't know a lot about firearms. When reading metric designations of cartridges the 1st number is the diameter of the projectile itself(or of the inside barrel diameter it's meant to be fired out of). The 2nd number is the length of the case that contains the primer and powder. R means the cartridge is rimmed, SR means Semi-Rimmed.
When reading "caliber" the .xx number is the diameter of the bullet(or of the barrel it's meat to be fired through). Barrels of .25ACP firearms for instance should measure to 1/4 of an inch internal diameter. The abbreviation or name after the caliber usually has to do with who designed it, what it was intended for, etc. (.25 caliber A
Different countries measure barrel diameter(and thus cartridge designation) differently. Some land-to-land, some groove-to-groove. A good example of this is 7.62x54mmR which has a different diameter than 7.62x51mm NATO or 7.62x63mm(30-06) even tho they're designated the same for barrel diameter. Also, cartridges are named somewhat arbitrarily or for marketing reasons sometimes(see .327 magnum vs .32 H&H Magnum).
People need to realize that a phone isn't bullet proof, just that many everyday objects can stop lower-power rounds. He's lucky to have that phone where it was, that's for certain, but a phone isn't a life-saver in that manner.Edited by DesertRat - 1/8/11 at 10:24pm
