12 gauge loaded with #6 or #8’s. Won’t go through the drywall, but will make a real mess of someone at close range...
Of course a load of rubber buckshot can be non-lethal and still get the point across. However at really close range, all bets are off...
Yeah that would work too.
A beanbag round is fairly lethal at 10 feet or less.
The point is that if I were in an apartment I’d want to stay away from a handgun. I don’t want a 9mm round going through a window and into someone else place.
You sort of have to consider your surroundings a bit. You have a right to defend yourself but not necessarily to wound or kill innocents near by.
In a crowded environment I believe a shotgun may be a better choice than a handgun. With either a beanbag or bird shot at close range you’re going to put someone on the ground and into the hospital. But, your range is such that you are not endangering those around you.
Just my position.
