We are all given our birth right of an opinion but I'd disagree strongly with you. Short barrel, small and weak round, handgun that can easily be taken from you and used against you, no way to attach a light, and then the list goes on.
Best hallway gun is a 10ga-20ga shotgun in either pump or semi auto with a sling and 18.5" barrel shooting buck shot. That's my opinion.
Huge range of shot from 3.5" 0 buck to a light recoil #1 buckshot with a nice flight control wad.
Never limit yourself to a pistol unless you HAVE to (example out in public).
I don't pocket carry so again that wouldn't work for me. I'd rather holster up with my 43 and have 9 rounds of Underwood 9mm +p+ over 5 rounds of 38. But if that is your jam, rock on!
