Hm. Here is what I think I want:
Old west style. Shorter barrel.
Side loading and perhaps side discharge. I think this means there will be two windows on the right side of the gun above the front of the lever. The lower gate is for loading.
AFAIK.
Side discharge is less important to me than side loading.
Ability to handle any .45 Colt round I want. Dr. Higgins said in an earlier thread that most of these guns will not gracefully handle the bigger .45 Cold loads. Not enough bullet spin, i think. A Japanese maker of Winchester made one that could manage these, but I wonder if this simply cannot be accomplished with the shorter barrel.
FWIW, where I come from these old lever action rifles were usually chambered in 30-30. For deer hunting in closed quarters. I suppose that is a thought, but the idea of a pistol and a long gun using the same round is delightful.....if it can do the same thing. Shoot a deer at 150 yards or so.
