i would agree with most of what you said, but it was colts manufactuing facilities that produced the most weapons and designs. including designs from browning and stoner. plus the pistol that won the west.
i personally believed this should have been a closer contest.
Samuel Colt is listed by name...not as a Manufacturer. I see your point but it would not be that much closer. Well, IMHO anyway.
There were a butt load of pistols in the old west and many were decent enough. The Colt peacemaker and other variants were among the best. But the run was not 100 years on the old single action wheel gun.
