Never play with your gun but how about if it's airsoft? It's sure fun to play with airsoft guns with paintballs but certain precautions must still be observed to avoid injury. Using airsoft gear is very important to protect yourself from hits, even if airsoft uses non-metallic pellets the hit impact is still equally painful. A pair of impact-rated goggles are required to protect the eyes for anybody participating using airsoft guns. Imagine being shot at least 10ft away and having no body and face protection, a body may incur minimal damage. Aside from goggles it's highly recommended to wear full-face masks to protect the entire face like the teeth, nose or cheeks.
Airsoft games usually simulate military battlefield situations which makes the games more realistically extreme. Players put themselves into obstacles and scenarios wherein there's no other way to go but fight. This is the kind of game ideally played by teenagers and older people requires discipline because it emulates use of real guns. IT may not be deadly like how a real gun is but has the capability of inducing a serious injury if misused. In any game most especially those which require shooting skills, utmost precautions must be observed. Making sure the proper gear is worn at all times is something every player must follow.
