History of the Wild West Guns:
Wild West Guns was founded by Jim West of Anchorage, Alaska in 1992.
They are known not for being on the Discovery Channel with their own TV show (Wild West Alaska), but also for being one of the best gunsmithing stores in the USA, if not the world.
They first obtained recognition for their Race Guns, and subsequently developed and introduced in 1999 the now world-famous CoPilot, a lever-action, take-down rifle, chambered in 45-70 Government.
Later in 2001 with the new 457 Wild West Gun proprietary cartridge, and  2021 the 30WWG and 35 WWG proprietary cartridges became available.
