Walker... Or... Dragoon...

[BruceB]

I had to put down a horse once; the Dragoon did a quick job of it.

Considering how heavy Dragoons are, did you shoot it or just clonk it over the head with it?

"Sam Walker approached Colt with specifications for a gun big enough to down a horse. By bludgeoning, if necessary..." -- some comment on some YouTube video on the Walker.
