I always have my EDC, typically an extra mag, pocket knife, and my k-bar. The car is always equipped with a full 1st aid kit, including tourniquets but in honesty wasn’t placed their for preparedness in case of gun/knife altercations. More for car and/or everyday mishaps. However, as things are getting crazier out there, I am planning to round the kit out with gunshot wound specific gear.
My on-person EDC is pretty basic. My range bag does contain a nicely outfitted first-aid kit that would definitely save at least one life under most credible circumstances.
