Just took my new Kimber Micro out for its first outing. Before going, I cleaned the gun and oiled it like I would my larger Kimbers. That cleaning and oiling included removing the extractor. I did not notice anything out of the ordinary about the extractor at that time.
I had 5 FTEs and 1 FTF within my first two boxes of ammo. At the time, I figured the problems were simply due to the gun being new. When I got home I cleaned and oiled the gun. After cleaning, I noticed that the extractor slid into its channel without any friction. In fact, the extractor slid all the way into the ejection port. This made reinstalling the firing pin stop very difficult. I think this looseness explains my FTE problems.
Has anyone seen this with the Micro? This is my first new Kimber. Is it common for new Kimber extractors to need tuning after just a hundred rounds?
Do I treat this Micro ejector the same as I would a full size ejector? I did have to put a little more tension into the extractor on my first generation commander sized Kimber before it would eject cleanly, but was used when I got it. It had quite a bit of mileage on it, unlike this Micro.
Here's the tuning method I used: (http://www.m1911.org/technic2.htm).
