This deserves a “like” and a “fuck yeah!”On the topic of shotgun capacity and the real world...
The internet has lots of theories about shotgun's obsolescence as a useful tool due to concerns about encountering multiple armored threats. As it happens, someone who has been to several of my shotgun classes was forced to apply a good deal of what we'd taught when multiple threats wearing level IV armor attacked the place where he was staying.
Apparently shotguns loaded with 1600 FPS slugs will shatter foreign made level IV armor plates...and the wearer of said plate can be put on the ground by the experience long enough to allow a followup shot to the CNS that proves definitive in stopping the threat. And this can be accomplished quickly enough that it can be repeated on the next couple of similarly armored bad guys coming up that stairwell.
In class I joke that it's unlikely that helicopters full of armored ninjas are going to break into your house so a shotgun will probably handle what you need it to handle.
The bizarre thing about training people to protect themselves is that something you say as a joke might actually come true. While there was no helicopter involved, a bunch of actual armored ninjas showed up intent on killing someone who had developed true proficiency with a shotgun and he managed to keep himself alive by using the light switch and an 870.
...and so I'll say again that if anyone in the world ever gets the notion to try and kill me, I pray to God they're fucking stupid enough to do it while I'm inside a typical residential structure when I have a shotgun handy.
