    Question: Channel liner?

    When you take the striker, extractor, safety&spring, and the extractor pin (or whatever it's called) out of the slide, is there still a channel liner that is plastic inside where the striker goes? Does it come out, how? And, does it need to be replaced after a while?

    Excellent question Hays; the Channel Liner is normally removed with a Liner removal tool. This is NOT something that should be attempted without need and the proper tool. The only reasons that I have ever seen to do such is because if the liner becoming deformed by excessive heat or by someone trying to remove it without the proper tool and scaring or otherwise causing the interior surfaces to become scratched. Such actions could cause a misfire, non-fire, or impede the striker and spring and cups. If needed a simple cleaning with a pipe cleaner is normally all that is required and of course FrogLube will not impede nor collect contaminants so it is safe to use. Otherwise I would refrain from any other type of lubricant in the Channel Liner. Hope this helps to answer your question. Be SAFE.....Shoot WELL....................PS, my Glock 22 Gen 2 has over 28,000 rounds on nthe original liner and there is still no need to replace it.

    Here are a couple of interesting little data points: the channel liner appears exactly once in the Armorer's Manual (©GLOCK, 2009), in the Exploded Drawing on page 13. There is no other mention of the part, no maintenance procedure including detail stripping, and no other mention of the channel liner tool (at least none that I could find after going through the manual twice). There are two mentions of inserting the firing pin assembly into the firing pin channel cut, but no mention that there is a liner in that cut.

    In the GEN4 ARMORER'S MANUAL (©GLOCK, 2010) the channel liner is not pictured in the Exploded Drawing on page 2, although it is included in the parts list. It is as if Glock didn't know the part is included in the Gen4 pistols (it is).

    Looking a little further, there is no current Glock channel liner tool in the Armorer's parts list, but there is an aftermarket tool available through Brownells (CHANNEL LINER TOOL for GLOCK® | Brownells). Glock does offer a Channel Maintenance Kit, consisting of a special set of five scrapers designed to clean out carbon from various recesses in the slide. It's available from Glock and from MidwayUSA (Glock Armorer's Channel Maintenance Kit).

    Talk about a "stealth" part!

    What have you used to place a liner back into the channel?

    A .38/9mm cotton bore swab on a cleaning rod:

    It's tight enough to remove the liner and loose enough re-install it. Just push it into place and hold the liner there with a blunt unsharpened pencil (for example) while you pull the swab out.

    The subject of the channel liner came up in my class. We were told that a tool with aggressive threads similar to a big wood screw was used to remove it. Once it was removed, it had to be replaced with a new one.

    To install a new one, just press it in using the Glock tool.

    When cleaning, make sure no oil is in the liner. I usually swab it out with a Q-tip.

    The reference to the 2010 manual by cohland is newer information than I have.

    For many years, now, the standard device used for removing channel liners from Glock striker channels has been a 5/16's inch carriage bolt. Like this -



    Removing the channel liner is, by the way, something you almost never need to do. The only ones I've removed have all been pulled out in order for the slide to be properly heated during refinishing. Some channel liners fit tighter than others. I've yet had to replace a loose fitting liner; they just seem to almost fall out. It's the tight ones that you might have to replace; but, my Glock tool box has plenty of them on hand; so this is never a problem.


    PS: Cohland, I like your suggestion; and I'm going to try it.

    I ordered a G19 BFG and had the slide ceracoated. When the firearm arrived I tried to disassemble the slide to oil it and could not get the firing pin out because they did not leave the channel liner in during the finishing and baking process so some particles of ceracoat got into the channel so the liner was not seated properly. My question is, how do I remove or clean the particles out of the channel so I can seat the new channel liner properly? Any help would be great, Thanks

    If you don't mind, who did the refinish work? What particles are inside the channel?
