A revolution mainly just takes strength of numbers; it's different from a war. The Berlin Wall fell without a shot, for the most part. And there's an awful lot of killing going on in urban areas of Israel right now with just blades. Likewise, 9/11 was accomplished with just tiny blades.

Could be useful for getting through metal detectors for an assassination. All you need to do is get the bullet through and you can hide that in a cap or a shoe.

A Glock is also largely made of plastic, but the barrel is made out of steel. Presumably this is because they would like to be able to fire it many times and because this greatly reduces the risk of injury to the user of the gun.
