Many shots with a 10mm Glock is better that one or two from a revolver i n a similar amount of time. The muzzle rise from a .454 Casul or other hard kicking magnum makes followup shots slower than a with semiauto weapon.
I agree. I can handle MY.44 mag shooting MY ammo because that is what I have practiced with since I got my first Redhawk in 1982. I tried a .454 Casull and that is too much for me. 10mm is VERY controllable. No matter what you use there will only be three seconds or less to get it done so you MUST practice because a 105mm howitzer firing beehive rounds won’t fit my chest holster…
