Realistically, pumps are just fine for HD. I doubt we can find where a homeowner had died because taking a round in an arm and not being able to work the action.I guess everybody misses my point about why a pump gun should not be used in HD.
If your in an exchange of gunfire with a home invader, and you take a round to either arm, your pump gun becomes a single shot. You can stay in the fight with a self loader, shooting one handed.
Short stroking is certainly an issue. Its one that can be eliminated though with the correct weapon for the job at hand.
99.8% of home owners ARE NOT going to get professional training, and fire at most a couple hundreds of rounds a year at a range.
With that said: a pump shotgun is not my first choice for a home defense weapon. It's a fine weapon, just not my first choice. I think one handed operation is probably the best argument for using a semiauto shotgun for home defense. Although you could go all Edmundo Mireles circa the Miami Platt and Matix shootout and use a pump one handed.
Bullets tend to slow down after passing though people. Also, don't use your family as a backstop.Shoot buckshot or other load through Sheetrock then ask yourself if family in other rooms will be safe.
