FWIW, the vid shows a controlled environment, with a traditional two handed stance, and a non retaliating target.
Change the scenario, 4:18 a.m. half awake, half asleep, no ear and eye protection, immediate intruder threat, it's dark, can't shoot two handed.
What changes?
Everything.....
If you are healthy enough, have good hands, no arthritis, and have some situational awareness, training, and the will, than this will work.
My father in law is 84, retired Army, Westinghouse Engineer, physics genius, but he is weak now. Ravages of time. His old 38 S&W is all he has in MD, of all places. I still wonder if he can handle firing it with standard 38's.
Splitting hairs for a BUG, or a second carry pistol, but whether its a .357, or 38 +P, or even 38 SPL, it will do the job for what its intended to do. If you run out of ammo in your primary, and have to go to your BUG, geez your in a world of sh** and I hope the cops are comin.
My M85 Taurus carries 5 rds. of GDHP +P's. and I carry with 2 Bianchi Strips. At home, different story, for an intrusion or break in, my pistol, usually 357 full size, or .40 S&W, is only buying me a few moments to get to the "critical dynamic, life threatening ender". Which is the Rem 870, or God forbid, the Sig556, or AK.
