I think a pistol caliber carbine is a better alternative than people give it credit for. Little bump in velocity, much easier controllability, ammo interchangeability, etc.
Am fond of the .44 Mag/.44 Special lever gun for many of the reasons mentioned here. An additional advantage is I typically load the .44 carbine with a heavier bullet, hotter hunting load (Winchester 250-gr Platinum, 'cause that's what I've got the most of right now; an equal alternative would be the Buffalo Bore "Reduced Recoil" — HA! — 250-gr lead Keith loads) that would be stiff in a handgun but is easy in the carbine. Gives me 9 (in the Winchester Trapper) hard-hitting rounds, backed with 240-gr JHPs for the reloads and the revolver.
