I think a bigger problem than short stroking a shotgun during a home defense situation would be falling down the steps or banging againsy walls because the majority of shotgun "training" is dedicated only to keeping the gun running and shooting enough ammo so you wade through hulls on your way off the range.- George
Running into a wall is a fear of mine with the shotgun because I have two sharp turns in a narrow hallway from my bedroom to get to the living room. I have to lower the shotgun and raise it again to get around the turns which is why I am thinking of using my pistol as primary home defense and leaving the shotgun in the bedroom for the GF.
Or give her the pistol and let her check on the noise while me and the shotty stay in the nice safe bedroom
