What if you got shot with a CO2 BB gun?

Answer 1

Any device that causes any part of your body to be impacted by a comparatively high velocity slug or anything like it can damage the body. In the case of the hand, you are looking at bruising, breaking the bones of the hand, possible penetration and resultant damage to internal processes including blood vessels, as well as other damage. Depending on the CO2 gun, projectile velocity can be as high as a handgun's and the dangers can be the same. Gas powered weapons have been used to kill people before, and thus warrant the same cautions firearms call for. While most CO2 weapons lack the abilty to fire a high-speed, high-intertia slug, and thus will usually result in superficial damage, even the low-powered weapons can do damage. Finally, much history on the subect of projectile weapons of all kinds yields the human race this important wisdom: Do Not Get Shot By Anything if you can possibly avoid it.

Answer 2

You go an see a doctor and have the BB removed
