  1. All 3 of the 9mm Gen4 Glocks I've shot hit dead center at 20Y. If all of your Glocks mysteriously have this odd POI issue, that pretty much guarantees it's a software problem...

    It's not all of my Glocks, I have nearly a dozen. It's just my late 2011 Gen3 gun and all 3 of my Gen4 guns. Recent mfr Glocks shooting left is not an uncommon issue. IIRC - The pistol-training.com test gun also exhibits the same issue.

  2. 226 magazines that are made in Italy are by MecGar, and the US made magazines are by Checkmate.

    My Checkmate magazines have exhibited some follower binding, even when brand new. I fixed it by scrubbing the inside of the mag body with 0000 steel wool and Kroil.

    The Checkmate springs do seem quite weak, much weaker than MecGar mags.

  3. I would also consider Apex Tactical.

    Prior to joining Apex Tactical, Scott worked for five years in various roles with well-known Master Gunsmith Bruce Gray of Grayguns, Inc. serving as an Apprentice, a Gunsmith and Shop Foreman for the custom gunsmithing operation known for specializing in H&K and Sig Sauer pistols. In his years with Grayguns, Scott also taught Practical Pistol shooting side by side with Bruce at multiple Grayguns Training courses across the United States.
  4. Anyway, feel free to offer any suggestions
    First, I'd start by numbering all of your magazines so you can see if the problem is limited to a one or two mags. In the future, when you have a lock back problem, write down the mag number.

    To eliminate your grip as being the cause, shoot the gun with only your left hand. Load up all of your magazines with one round and keep cycling through, if it always locks back, it's your grip.

  5. I'm surprised to hear about so many issues with an OAL of 1.15" in Glock magazines.

    I've shot over 17K rounds of Federal AE 124g ammo this year, it measures 1.151", I didn't have any issues.

  6. Some of the more recent Glocks have MIM ejectors instead of whatever type they used to use... whether MIM or not, if they work, they work, thing is the newer MIM ones don't seem to be machined or fit exactly quite the same way as the older ones as with all of my trouble-free Glocks the ejectors will fall right out of the slide and into your hand just by tapping on the slide after you've removed the spring-loaded bearing thingy and striker block/plunger and spring, many of the newer ones don't do this until after they've seen some real use.

    ck1 - I think you mean extractors, not ejectors.

  7. I also had to replace my extractor plunger spring a while back after mine decided to up and GTFO when taking the slide plate off, so hopefully it isn't getting weak or anything, but i'll check that too.

    I would double check that you put the plunger & spring assy back in correctly. The metal plunger should touch the extractor, not the plastic spring loaded bearing.
