*I* would be worried... the typical 9mm handgun has a muzzle velocity of
about 1200 feet per second, and the bullet leaves the barrel with a kinetic
energy of around 380 ft-lbs of force (about 520 joules). Consider the havoc
that bullet can wreak.
Now think about a 10 mm meteorite particle moving 22 MILES per second, and
what kind of force THAT would have...........
