Bobby, welcome to the site from Tennessee. A lot of us like to use Freedom Munitions 147gr 9mm ammo for break in and general range use.
I would say Yes, a lot of malfunctions can be traced back to poor ammo selection. Never had a problem with any of my Kimber's. I use the factory mag and KimPro Tac mags and Joes1911magmania magazines, he sells on Ebay and has real good magazines at a reasonable price. A lot of us use his magazines.Hello, and thanks for the information. I assume the ammo I mentioned is not loaded high enough to ensure full functionality. I'll give your suggestion a try.
May I also assume this is a common problem?
I called Kimber today and Jay was very helpful. He took notes and told me that if the weapon doesn't straighten out by 250 rounds, I could send it back to be worked on.A while back I got 2 Kimber Ultra IIs. One in .45 and the other in 9mm. The .45 had to go back for the same problem you are having. It was fixed and have no further problems. The 9mm has been perfect right out of the box. Never a problem. Great shooter. I have another Kimber in .45 (custom Classic) that I couldn't fire more then 2 rounds before the thumb safety locked the hammer. It also went back and no further problems. I believe with Kimber, it's a hit or miss proposition when you buy one. (kinda the luck of the draw).
They are supposed to be fully tested before shipping (according to the propaganda), but then there's a lady down the street that will read cards and tell you your future, for a fee.
In my opinion, the overwhelming majority of 1911s need a break-in period, and 250 rounds seems optimistic. I own several Kimbers in various sizes, and they have all started off with the usual malfunctions. After a while, they perform absolutely flawlessly without any need of work being done on the guns.This disappoints me somewhat. For what I paid for the weapon, I should be able to reasonably expect NO malfunctions right out of the box. I've bought Glocks at half the cost and experienced NO malfunctions after thousands of rounds. Now I may have to send my weapon back to Kimber so they can 'grind' on it, further opening the tolerances?
