This was my first Kimber, and the first one to go away. Mine was an earlier Series II with the external extractor.
When I first got it, I liked it quite a bit. It was accurate as hell, and some online digging found out the mod for the mecgar para mags to make them fit ($13.00 13 rnd magazines). I did have one issue right away, the thumb safety stuck out from the edge of the pistol and dug into my hand while shooting. A few seconds with a dremel to remove the excess edge took care of that problem.
It was pretty stiff, and had some feeding issues. My solution was to shoot it in. After what I thought was a good enough break in period (600 rnds) with it still not feeding ball reliably, I sent it back to Kimber for some work. They sent the gun back without doing anything to it and told me to shoot it more (another 600 rounds). I was annoyed with them to say the least. I talked to their customer service reps and let them know that I thought a 1200 round break in period was ridiculous. My gun shop had just started to get kimbers coming back in with problems, so after digging around online, I found out about some feeding issues with the series II extractors. I'd actually not checked that out since it was an external extractor. I checked the tension on mine and found it was way too tight. I actually had difficulty getting a round under it by hand.
I sent it back to kimber again for repair, this time with a zip tie with my initials on the bottom side run thru the gun. The gun came back 8 weeks later with my initialed zip tie still on it and a letter saying they'd replaced blah blah parts and done some polish work to it. I gave Kimber a call and ripped into them big time, as did my manager. Sold the BP Ten II & my Custom II and won't own another.
Fast forward about 6 months, one of my friends picks up one and it shoots absolutely flawlessly after the inital, brief, breakin period. I think the gun is fine, just Kimbers external extractors have some problems. Hence them switching their guns back to internals in April of last year.
BTW, for a cheaper alternative, BUL Transmark is now using Charles Daly as a US importer.
