    kimber 22 conversion mag questions

    I have a kimber 22 rf conversion unit sitting atop my kimber custom 2 frame. Lately, I have had several instances where the next round will not feed, it extracts and ejects the round fine out of the chamber, but the next round will not feed/load. I have lost count of how many rounds I have put through, over 2k rounds. I have several different kinds of ammo through it, cheap remington golden bullets, winchester 333 packs, several different federal/american eagle loads (automatch and american eagle mostly). The latest has been federal bulk. Is it the magazine springs, and are there any other rimfire conversion mags other than the kimber that will work with this conversion unit?

    This problem was discussed in our e-zine review of the Kimber conversion. IIRC, it was solved by the tester by disassembling the magazine, smoothing the follower, and lubricating the magazine with dry graphite.

    Ah, yes: http://ezine.m1911.org/showthread.php?t=142

    It came as a surprise, then, when part way through the accuracy portion of our evaluation we began to experience random failures to feed. When these occurred, they were complete failures to feed. The slide cycled and closed normally, the disconnector reset, the trigger pulled and the hammer fell. But … the hammer produced a “click” rather than a “bang.” Partially retracting the slide after these clicks invariably revealed that there was no round in the chamber; the next round was sitting well down in the magazine, below the point where the advancing slide could strip it from the magazine and chamber it. This occurred (at random) with multiple types of ammunition, and it was irregular enough that we couldn’t attribute any pattern to it.

    After returning to the man cave, we played with the magazine and noticed what seemed to be a slight “hitch” in the movement of the follower in the tube. It should be noted that the Kimber conversion uses polymer magazine bodies as well as followers. Thinking that perhaps polymer doesn’t slide well against polymer, we disassembled the magazine and used a small piece of 600-grit emery paper to polish the sliding surfaces of the follower. We also dusted on some powdered graphite when the magazine was reassembled.

    Check the top of the barrel and make sure the firing pin has not Peened the end of the barrel. The Kimber unit does not lock the slide back on the last round. It is very easy to drop the hammer on an empty chamber.

    I've seen this happen before on other 22's not sure if the firing pin is long enough on a Kimber to hit the barrel without a round in the chamber.
