I have a problem with wanting replicas of guns that I later find out were never made or were not made in that caliber. I want to get a 44cal with a short barrel. I like the 1851 Navy Sheriff, the 1860 Army Sheriff and the US Marshall. The 1851 Navy Sheriff is my favorite of the group. I guess it does not matter too much either way since they are reproductions, but which shorter barrel 44 cals were actually produced by Colt.
