The CO2 will leak. The bb will not do more than bruise the assailant even with a fresh CO2 cartridge. I would stick with the Glock. Or the KaBar. Or a rolling pin.
I have heard of people being scared by bb guns that look like real guns. Sometimes scared enough to shoot the guy using the bb gun.
I guess I should say I base this on a Crosman that looks like a Walther P-38 that I ventilate aluminum cans with. It won't penetrate tin cans. You may have some other weapon in mind.
