The gun was made by Polytech (or whichever Chinese factory that was making the Cimarron/TTN 1878 hammer shotguns at that time). The Chinese cannot make cartridge guns for export to the USA, but they can make percussion. The idea was something like they would make percussion guns that would be very easy to convert to cartridge guns once they got here. Possibly even with SAA type models. But the idea did not come to fruition beyond this sample. I don't know if they had an actual gun to copy, but I remember Bruce, the factory rep, meeting with Mike Harvey at Shot Show and taking a bag of parts with him. This gun's action does function, but it feels very clunky. Given the chance to shoot it, I think I'd pass! It sat upstairs at Cimarron in Mike's office for several years, so I picked it up once and snapped a pic.
