    I own a Gen 3 G27 and I recently purchased a Gen 3 G23. One of the reasons I bought a Gen 3 G23 instead of a Gen 4 is so that I would be able to swap the G23 barrel into the G27 when I wanted a little extra barrel length (supposedly this is possible) I tried it today at the range without success. When I tried to fire it, the first round would go off and eject, and when it tried to cycle the next round in it would hang up with the slide almost all the way back. Is there a way to fix this? Has anyone else experienced this?

    G23 barrel will drop in and work with a G27.
    Mine works like aces.
    Either;
    1) You have a third party barrel that needs to be fitted
    2) Your ammo is (*&_(*&&((.
    3) User Error

    Did someone tell you that you couldn't do this with a Gen4 barrel?

    1. The barrel that I used was the stock G23 barrel.
    2. The ammo was Federal 180 fmj bulk pack from Wal-mart which fired fine when the pistols were in their original configuration.
    3.I don't think was any user error involved. It's a simple thing to do.

    btw Thanks for the velocity info. There isn't a lot of difference, but I like to have options and versatility.

    I wasn't sure if it was possible with the Gen 4 barrel. I know the slides and springs are different, so I played it safe (or so I thought) and stayed with the same platform.

    Some of the newer barrels that have more chamber support often require matching newer magazines. I think they have magazine follower #5 or newer. (maybe #4 but I'm almost certain the change in 40 S&W is at follower #5) I bought a newer Glock 27 barrel for my early Glock 33. The rounds sort of bounce off if the feed ramp into the chamber where I think with the older barrels the rounds fed more smoothly in the chamber.

    This is very interesting. I had 2 new G23 mags and 1 old "for law enforcement only" mag. I'm not sure which mag was in the gun at the time. I'll try this again next time and make sure I am using a new mag and see if it makes a difference. Thanks for the info!

    My 23 barrel does fine in my 27 just as the 35 barrel does in my 22.

    That's really bizzare? It's just drop in.
    Did you try your G23 mags in the G27 with the G23 barrel?

    I didn't think of the followers like the other Poster suggested?

    This is what I know about followers:
    I have three new 357 mags (G33 & G31) they are all #2.
    I'm pretty sure that's the latest for 357 Sig.
    My 40s (I have a bunch) are all #9.
    And my 3 new G26/9mm are all #6

    All of my four lengths of 40 followers are #9.
    I have all factory mags for;
    G27/G23/G22 and three 22 round Big Sticks.
    They all work great.

    BTW if it is a follower issue?
    You can get the followers separately and upgrade your old mags with new followers.
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    Sorry I can't be of more help.
    Good Luck

    An "old" magazine may have a worn, weak spring in it.

    When using Glock 22 and Glock 23 magazines in the Glock 27 without a grip extension sleeve, the pressure from the fingers on the magazine can cause the longer magazines to "tilt" in the pistol frame and nose dive the cartridges in front of the barrel. Try the G23 barrel using only G27 magazines and if that works, add grip extension sleeves to the Glock 23 magazines.

    I tested the G23 barrel in the G27 again this weekend. The first magazine that I tried was a G23 mag (newest follower #9)(180gr Federal HST). It jammed three times in a row. I tried a different ammo (fmj) and it still jammed. Then I tried a G27 mag (follower #8) and it worked fine. I fired a couple of mags full with the G27 mag. Then I inserted a G23 mag with a sleeve and this time it worked fine. Then I took the sleeve off and tried it a second time (same configuration as the first time with no sleeve) and THIS time it worked fine. Go figure.

    I've heard that if you don't use a sleeve with the extended mags you can pull the mag and sometimes get FTF. I generally just run flush G27 mags for Self Defense these days and the rest for range work.

    Everyone is going to get pissed at me for saying it, but too bad.
    I truly believe my G27 runs more reliably, and is more accurate,
    with Storm Lake 40-9mm conversion barrels and G26 mags.
    I've got SL9mm G27 and G23 barrels and the damn thing just sings.....[​IMG]

    And if your concerned with 40 ejectors and 9mm ammo?
    Mine throws 9mm brass like somebody entered a launch code.
    1 box each:
    Winchester Ranger T 127 +P+
    Speer Duty GDHP 124 +P
    Federal HST

    I had a very similar issue. Not with the barrel but with the mags. When I used a G27 mag with my G27 - it worked perfectly no matter what ammo I used. When I used a G23 mag with my G27, I'd get FTF's and that was with a spacer as well. Through lots of experimentation :supergrin:, I found out that if I used Blazer aluminum, the 23 mags worked in the 27. But only Blazer aluminum was perfect. Other ammo including JHP had issues. So - I'd suggest your solution may just be different ammo, not necessarily different mags. By the way, the latest follower on G23 mags is #9. I had an issue with a #8 follower in my new Gen 3 G23.

    Good luck.

    Hmmm...anyone thread these barrels for a suppressor?

    @ barth:
    I have a 40-9 Lonewolf barrel for my G27 and my G23 and they both have functioned flawlessly. I can put the G23 40-9 barrel in the G27 with absolutely no malfunctions no matter which magazine I use. The chambers are tighter than OEM Glock. I found this out when shooting some reloaded ammo. The Glock OEM would chmber it but the Lonewolf barrel would not. I solved this issue with an adjustment to the loading procedure and now can shoot reloads in the Lonewolf with no problems at all. I can also get better accuracy from the Lonewolf barrels. I think my next barrel will be a 357 sig bbl for the G27. I love having the versatility and options.
