I am sorry to hear about your problems... I had some serious issues with a Montana and had to send it back to Kimber.. The chamber was out to the point factory ammount would not load.. they worked the chamber.. I got the gun back and the best I could get it to do was 2.5 to 3 inch groups (three months of reloading and 2 factory rounds later, I sold it.... I then swore I would never buy another product from Kimber. (one good choice)
They were very helpful on the original repair.... pain in the behind on the accuracy problems.
If Thompson Center is America's Master Gunmaker... We are in a lot of trouble.
