Don't bame the Carbine.
Your tipical IDPA type pistol Shooter(s) wouldn't dream of engaging copyrighted "A" Zone only hits at 50 to 75 yards on a regular basis.
A tipical M1 Carbine shooter, with a minimal amount of training, will drill the "A" Zone with speed and accuracy and ease at those distances; even before he eats your lunch.
At close distances, the M1 Carbine is, by design, wickedly fast... bullets first...with 357 Magnum ballistic power.
And if that doesn't work, M1 Carbine shooters have been known to appear, "Bayonet Equipped", with the option to slice, poke, slash, or just club their way to solving their problems.
