shotguns
Just my two cents....ammunition is a important consideration for defense....and probably as important as anything else about the shotgun.
While a cop, I have seen two BIG muscular guys each take relatively close hits....both with 3" mag, one with number 6 shot and the other with BB.
One was a ambush intended to kill him, the other was a dispute over a woman..
One of the guys walked about 8 blocks to the hospital to get treated....holes all over and breathing problems, but nothing else to major.
The other hit with BB sat and talked with me waiting for the ambulance.....he had some nerve damage in his right arm...(didn't work to well) and was pretty pissed off, but not much fight left.
I am sure every hit yields something potentially different and OF COURSE, the ammo....had it been heavier shot, probably could have easily been fatal...
The point is, ammo selection is important......forget thinking just because it is a shotgun that it will stop someone in their tracks.... if the perp is not hit well, and or the shot is not the right stuff......don't ever assume the battle is over till the fat lady sings
or whatever or however you want to think about not making assumptions once a shot is fired....you may get a surprise.
