I didn't get shot, but id say the LB/ft of energy delivered to my vest was WAY above that from a 12 gauge. no bruise where the vest was covering my back. (posted this before)
I fell 5 feet and landed on a square steel catch basin that was about 3/8th inch thick , it went across by back at an angle starting about right hip up and across to left lower ribs. I was wearing my issues iiia vest in an internal carrier under my shirt. I bruised my left kidney badly.
When I was laying on the deck of the boat all I could think was I can’t feel anything below where I’ve been impaled by the boat. I thought I had been stabbed/impaled on something and it was sticking out of my back. Coworker was like "OH SHIT, when he saw my back(which didn't help..), turns out that id taken red paint from the catch basin and embedded it in my shirt. Never broke skin. I was in great pain due to the kidney that had been hit, worse than a kidney stone, I drove my self to hospital with a 5.5MM kidney stone stuck in the tube, this was worse and made me non functional. Ambulance was called. When I got to the ER the X-ray showed no spine damage and I was taken off the backboard. Kidney damage was just bruised. My back had a line bruise from lower right hip to just where my vest started about an inch from where my spine was.
They tell you in training that the vests help with car accidnets and falls too.
2 weeks in bed on serious pain pills and muscle relaxers, i don't really remember the 2 weeks.
