    I have a Kimber Compact Stainless that I really want to love, and I do except for the problem of the occasional empty case mouth catching on the barrel hood during it's ejection. Stops the gun. I can't rely on this gun for this reason. Sent the gun to Kimber and they supposedly "adjusted the extractor" and returned it to me asap. Extractor seems well adjusted and I would guess this may not be an extractor issue. But I'm irritated that I got the gun all the way back to Kimber and they didn't get this fixed. Usually happens on the next to last round during rapid fire and has happened with a few different Wilson magazines designed for use with the Officers /Compact frames. Ammo is factory fresh Win, PMC, AmerEagle JHP and FMJ.

    I believe the rim of the case is still in the claw of the extractor when the mouth of the case gets caught on the hood of the barrel... when I pull back the slide to clear the gun, the empty case doesn't fall out, I have to work at removing it from the extractor. Does that information indicate anything?

    The factory standard recoil spring is 22#. I measured the weight of the spring in the gun (which was rated as a new 22# spring 400 rounds ago) and it's just around 20# by my measure, which I think is accurate + or - 1 pound. I have a used (900 rounds) spare spring which measures just a tad below 20# and another (brand new - rated 22#) one which measures about 21#.

    Anyone have any ideas what could be causing this problem? I suppose the easy approach would be to try a lighter or heavier recoil spring? Or is the ejector not doing it's job? Confusing to me.

    .. is the consensus that I should try the heavier recoil spring?

    Thanks guys... seems like this should be simple, but it's driving me nuts. Gun has about 1500 rounds through it so far and I still can't rely on it. Aside from this problem, the gun runs well and is quite accurate.
  2. It sounds like the extractor is doing it's job if it still has ahold of the case. I would look at the ejector. Try replacing it with a longer one and see if that helps. It may not be kicking the case out soon enough to clear the ejection port.Let us know what you find.

    If you have to ' work at the extractor ' to free the case ,the extractor is the problem. Kimber didn't fix it correctly.
