A shotgun will certainly stop the threat if the situation is favorable to a trained shooter. Few folks could move effectively through a structure w/ multiple doorways and T intersections w/ out training and practice. Adding a long gun to the problem increases the degree of difficulty. Only the lightest of shotgun pellets will not penetrate 1 or more walls. Can you make a headshot on a scrote holding a hostage in front of them at 15 yards w/ your choice of loads. For many people weapon retention in in an entangled engagement is more probable w/ a handgun.
Move your fight to the outdoors and learn the difficulty of running that shotgun from the prone and the joy of 5-7 rounds in your gun w/ slow reloads. Aimed fire vs. point shooting is no longer even a subject of rational debate. Much has been learned since 9/11 and the the average civilian can take a well run FoF class and prove for themselves what works for them.
No tool replaces a determined mindset which leads to focused training and deliberate, constant practice.
YMMV

But bad guys piss themselves and hightail it out of Dodge at the sound of a shotgun racking.
