Okay so here is my update. Kimber customer service get an A+. In less than two weeks I shipped and got the firearm back. They reamed and polished the chamber, adjusted the extractor, and replaced the recoil spring. They sent it back dirty after firing 36 rounds through it but o big deal. I did a quick clean and shot 100 rounds of sig ammo. Two different lots. Of the 100 rounds, two had an issue at the feed ramp. What's different though is I could drop the mag and put it back in with no issues! It only did this with the Kimber mag and it was when the gun was really heated up. It still ejects cases like a reward bullet. Never stand behind somebody shooting one of these lol. I'm glad I bought it and I do love this gun now that it's fixed. Now I just need to get a threaded barrel...
