I had Thompson’s custom shop, “ Fox River “ or something like that build me a 45 acp barrel for my contender years back and thread the barrel for my suppressor. They told me it was the only one they had ever done. It was shortly prior to them closing their doors.
I’m traveling for work again but when I get home I will snap a couple pics. I very rarely ever shot the thing. It was not the cheapest project but pretty fun. Would be a killer 45 Super shooter.
