No thanks to either. If I were in a stationary defensive position, maybe. If there were even the slightest chance that I'd have to move through tight, dimly lit hallways, etc.,(house clearing) then retention becomes a BIG factor. There's just to much surface area on a long gun for someone else to grab onto. Once there's a struggle for retention, all bets are off and that would be a far nastier scenario if you're up against two intruders! Just one opinion, but I'll never be convinced that anything beats a quality 357mag revolver with a barrel of 4 inches or less, for HD.
