I have not been in a gun fight(thank God). But I have hunted many years, you get pretty excited seeing that big buck or a flock of ducks. I don't think recoil would be of concern if it was a you or them situation. Just my 2 cents.
2 possibilities here. Either you aren't remembering what was exactly said or the "trauma room nurse" was full of hooey. At normal room distances the shot pattern is not going to open up very much and will act almost like a slug in a solid pattern. Very little spread. If he actually said it barely penetrated the skin then he had not seen any shotgun wounds. He wasn't a hunter either or he would have seen the effects of shot on heavier skinned and feathered animals than a human.I read a lengthy post by a big city Emergency Room Trauma Nurse a few years ago, who has significant experience treating all types of gunshot wounds. He has worked on multiple shotgun wounds incurred by people at close range - think room-distance. His recommendation based on his first-hand observations are to NOT use small shot sizes for home defense. He has observed multiple instances where someone was shot at across room distance with birdshot, where the shot barely penetrated the skin. While it certainly made a mess that required medical attention, the shot DID NOT penetrate to the vital organs.
While birdshot may occasionally prove immediately fatal in gunfights, I cannot personally recommend it, nor use it personally. Based on his experience, and the experience of numerous law enforcement agencies, I personally rely on #4 buckshot inside the house. I wish that I had copied the Trauma Nurse's post and saved it for future reference, but, alas, I didn't.
I've kept #4 buck for home defense for many years, but in my apartment I imagine birdshot--#4, #2, BB--would be about as effective. Range would be very close, and any shot load would arrive almost like a solid mass.
What are the laws in your country regarding using deadly force to protect yourself? THAT might be a factor in what shot size to use.
