For GSW I use a trauma kit: hyfin vent chest seals, tourniquet, clotting bandage, shears. In my range bag and/or car.
For my home first aid kit (which I would put in a car if going to an event, but I rarely do), I have one of those prebuilt EMT kits with some additional trauma items, items are staged so I can stop bleeding from a shop injury long enough to get to a phone (if I'm not carrying it, which I usually do) and call an ambulance. Something like this.
I have the routine "first aid" stuff in separate kit that's at least 10 years old, that I really should go back and refresh.
As for training, I've had various trauma classes a long time ago, and more recently BLS and was ready to get ALS (at the beginning of covid, when it seemed like covid was really a problem). Also, got an education-by-osmosis by flashcarding my ex (and reading all her books and notes when she wasn't studying them) while she was in RN school. Honestly, I knew most of the stuff from prior reading, but I was glad not to have to take the tests.
