I just don't see how 3-4" of barrel makes a rifle "handier".
If extra barrel length was an asset all the military door kickers and police SWAT teams would not bother with carbines.
And in the dense alder/willow pucker brush wounded brown bears hole up in I know for a fact that shorter barrels give you an edge ! A shorter overall length is also the primary advantage African PH's list for double rifles !
