yea idk I thought about it a lot, in some emergency of course would have my pistol 1st but I think I would go for my ak before the shotgun if I had the chance, doesn't help my shotgun is a 27inch barrel and my ak folds up, I have a small house so its kind of a tight fit, that and my shotgun is a pump so if its more than 1 attacker, idk I am just more comfortable with the ak. I only ever shoot birdshot from my shotgun at skeet so not even sure what it like to fire the 00 I keep in it or fire at anything that is not an orange disk for that matter.
Run out a box of 00, just to see. It is very different, to me from a field load, say #7. And H will know but, I think I remember something like 9 pellets of .32 cal in a 12 g magnum, 00?
With a pump, that sound alone makes two attackers huddle together in fear, just to hear it. And they make an easy target that way. But, I will say this, if you can't shuck it one handed with either hand, go practice.
You could put on the tactical grips and stocks, but don't shorten the barrel below 19" (safe side). I have (strike that) I know of a Mossberg pump that loves me. The feeling is mutual.
But, remember Science of the Lambs? What happened to agent Starling's dad? Like sheer misses at close range with pistols, the short shuck can end it for you, badly.
