Do you possess the skill to adequately use a blow out kit, a first aid kit? I carry a blow out kit in my "kit" at work, at home in the car along with but separate from my first aid kit.
To those unsure, a blow out kit is really intended for if "YOU" get shot so you can treat yourself or your partner uses yours to treat you.
I do not walk around with a blow out kit. With the skill set you can improvise a lot of bandages temporarily until the Calvary arrives.
My rifle and pistol are tools, I am the weapon.
