No, there are tons of people that can kill at 100 with a .45 1911, maybe you’re not that guy. No perhaps and no carbine, I’ve shot against lots of them.
45 acp at 25 yds will drop 6”.
Up close and personal it is hard to beat.
45 acp only has a muzzle velocity of 850 fps in a pistol.
you may top 1000 fps in a carbine.
I like carbines, but not for 100 yd shots on bears.
