Back in May, I wrote about a problem I had with my new GLOCK 43: the magazines would intermittently hang-up when I tried to insert them. A little bit of time with a Dremel didn’t completely resolve the issue at first, but a few trips to the range, and a lot of insertion/re-insertions of magazines during drills later and there’s no issue. Really, there hasn’t been any problem in months. For the record, GLOCK’s customer service . . .

after hearing my concerns, sent me a new magazine catch. I haven’t bothered installing it, as by the time it arrived via U.S. Mail, the problem had gone away, and I operate under the assumption that there’s no point in fixing something that isn’t broken anymore.

Which is good — the GLOCK 43 has been riding on my hip more or less nonstop since then, replacing the GLOCK 19 and Kahr P380. I’m planning on taking a defensive tactics class with it this fall, so we’ll see how it runs under more stress, but other than this one hang-up, it’s been a solid performer.

So…GLOCKs. Even when they’re not perfect, they fix themselves.

        • all ‘problems’ with GLOCK can be corrected by replacing the part that’s listed in the owner’s manual as “firearm”.

          Luckily, every other gun manufacturer makes this replacement part. I prefer Beretta ’96 (’cause people think it’s “snappy”). Or Sig Sauer P226 (in the same caliber for the same reason).

      • Adam – I have absolutely nothing against Glocks. If you like black plastic bricks that spew lead all day long then Glock is your go to weapon. I own a 17 and love shooting it, but I would never sleep with it. Now my Sigs, I wash them off all the time.

  1. I saw a video about this exact issue. He could consistently duplicate the problem by inserting the magazine at a particular orientation. My guess is the problem isn’t really fixed, you’ve just (subconsciously) adjusted your behavior to hide the problem.

  2. Ok, so…
    1) Does this mean that Glock has changed the design of the magazine catch on the 43, and new guns are now manufactured with the improved version?
    2) If so, how do we know if we’re getting the improved version or the original?
    3) What is the starting serial number of the improved version?

    Call me demanding, but this blog would be more useful if it had more actual, useful information and less anecdotes about people who modify their own guns.

  3. The glock wasn’t having failures, you obviously were not using it correctly. Glocks don’t have issues of any kind, it’s only their operators. /sarc.

  4. The Smith & Wesson Sigma 9mm has the same problem. Had to dremmel the mag at a 40degree angle to make it slide properly.

  5. I got one of the first G-43s in April. It works great.

    That being said, why would you take a Dremel to a new, under warranty, gun. Just send it back to Smyrna.

      • Point taken. Ultimately they are tools, and don’t need to get ‘excited’ about them. That’s not their purpose. And they are certainly damn reliable, durable, low maintenance tools at that. Just don’t really enjoy them as I do say a fine revolver, or my CZ’s, or a good 1911. Hence the fat chick reference. Can still do what you gotta do, but not exactly an exciting experience like say a 120 lb hottie blonde. (sorry for being a bit crude there, but I think you get the point).

  6. I’m glad to hear that since I still haven’t made a subcompact 9mm / .380 purchase. The G43 could be a good gun for the wife’s CCW if she can find the time to take the class. It’s nice and light with a decent sight radius.

    Shoot often and hard enough and you’ll wear out mag springs and / or beat up feed lips. That’s what was causing failures in my old Glock 35. The range guy was convinced I was “limp writing.” Just with that gun, somehow, and not with any others. I won’t be taking advice from that range guy anymore.

  7. My best friend’s sister’s boyfriend’s brother’s girlfriend heard from this guy who knows this kid who’s going with the girl who saw a GLOCK malfunction one time.

    • I’ve been shooting a lot of idpa in the last two years and have seen glocks stop more than anything else.

      • For me its be dirty DGI AR-15s, then 1911s. Competition Glocks probably have a bunch of mods which make reliability comparisons moots.

      • A lot of people think, “It’s a Glock, it doesn’t need to be cleaned because I hear there’s a Glock at the factory that has been fired 100,000 times without being cleaned – works every time.” I thought that at one point in time. A weekend training at TDI in Ohio changed my mind when one trainer said to respect the gun, clean it. That was eye opening. No matter what the manufacturer – Respect the gun, clean it after shooting, keep it lubed, and change all the springs; mag, recoil, etc. regularly, and you will rarely have a problem. It’s a piece of equipment – take care of it and it will serve you well. Yes, there are recalls on some guns. Some guns take 500 rounds or so to break in.

  8. Mine never had the problem. Sometimes it would feel like it would get caught up, but it didn’t.

    Also, Glock also sent me a brand new mag catch after my knife modification didn’t fix the problem I didn’t have.

    So yeah, they’re awesome for customer service. I’m still carrying my G43. In fact, it’s on me right now.
