I think it should be understood that there really wasn’t anything inferior about these trade rifles. Yes a high end rifle, like a Hawken was better quality, but, it wasn’t monumentally better. In fact some trappers, and explorers, got trade rifles early on, and never felt an upgrade necessary. Many upgraded to a Hawken, or something equivalent long after their day in the fur trade were over. Kit bCarson carried a Henry trade rifle before he bought his first Hawken, and T.J.Hall came to California from the fur trade with Fremont, carrying a Daringer trade rifle.
I think trade rifles were more popular in the West, because they were more robust that the average “Kentucky” rifle, and bigger caliber.
