A significant number of experienced emergency medical professionals do not carry or use hemostatic agents, probably for the same reasons you do not.
I'm not used to it, so I'm very iffy on it. I might talk to a few docs that I know and see if they have opinions about it.
In my humble opinion, the smallest, safest (for the non-medical specialists) and easiest GSW kit to carry, is a SOFTT-W, H&H Z-fold sterile gauze and 4" Israeli Bandage. Simple, fairly cheap to acquire, no hemo's, chest seals or needles (so no treatment of tension pneumothorax), but good stuff to carry everyday. (I carry a CAT simply because it's what I have but the SOFTT-W folds smaller.)
1. Apply TQ
2. Stuff wound with gauze
3. Apply Izzy dressing
I agree. Those will definitely get the job done, as long as bleeding is your issue and not a compromised airway or a pneumo. I'm trained in the use of some things, just not a decompression needle. Until I get the training, I probably won't carry one, unless I get a heck of a deal on one.
