Lone Wolf Glock Generation 4 SS Guide Rod Complete Assembly

I am a Glock fan. Have been ever since I had my first one. That said, there is a time and place for polymer. And certain components that take a lot of impact abuse are probably not the first place I would eschew the use of steel. The plastic guide rod is one component that can chip or break which can then cause a number of ejection of feed problems.

Lone Wolf Distributors has a complete drop in replacement for Gen4 Glocks starting at $29.95:
Special features include:

  • Solid stainless steel guide rod
  • Precision CNC machined to accept a removable Allen head tip, for easy spring changes.
  • 17-7 stainless steel recoil spring.
  • Spring weight calibrated to factory weights.
  • 75% heavier compared to OEM part. (1.4oz vs .8 oz)
  • Available as a highly polished version for only $10 more. High polish option provides a smoother, quieter operation.

Have any of you upgraded your guide rod?  If so, please drop a comment with your experience.  (If I had a Gen4 I would give it a try for $30–not that I have had a guide rod go out on me).

    i have not tried them, but I think brass stacker has some drop in replacement glock parts

  • Bruce

    I’d have to see one fail to convince me to replace it. Of course, my Glock is a range toy. Never really thought about it before, my carry guns all use steel guide rods…

  • Hunter

    The glock RSA is plastic for a reason. The whole frame flexes during shooting, the RSA flexes with the frame. It’s designed that way.

    • Gregory

      It’s plastic because it’s cheap and saves weight.. Otherwise the sights wouldn’t be cheap plastic either.

      The guide rod is usually one of the first pieces to break in a Glock, as well, there’s no benefit to plastic besides the weight.

      • The stock plastic sights on a Glock are due to insane BATFE import regulations on foreign firearms. They have to meet a “points system” in order to be legally imported.

        • Al

          Glocks haven’t been imported assembled in years, the parts are imported, and assembled in Smyrna GA. The frames are made in the US. A plastic adjustable rear sight used to be made for importation points, but the current plain plastic rear sight is just what they come with.

    Maybe now that these are out, Lasermax will do a dual-spring glock gen4 guide-rod laser? The one thing keeping me from jumping in is their gen4 guiderod unit uses a single spring, and that just seems like a step back.

  • JR

    Not all design choices are driven by cost. Perhaps the guide rod is polymer because that’s what best for the design?

    • Hum my first thought is probably not. At least I don’t see why it would be beneficial over steel.

      • Al

        Well, the plastic is lighter weight. And cheap to replace as a unit, when my dept. issued Glocks I replaced them every 2000 rounds, cost about $5 per gun. The only actual breakage reported was if the gun was incorrectly reassembled, the lip on the tail of the rod would shear off.

    • herb

      Yeah, I like the idea, at least if it only costs $30, of just going with something practically indestructible. But then ever since seeing a slow motion video showing the frame flexing and parts rattling around I’m convinced that while Glocks undeniably work fine, they’re weird. I’d be worried about throwing off the symphony of flexing and rattling by adding a stiffer part.

      Also I find them excessively top-heavy to begin with, wouldn’t want to add to it.

    I’ve had a stainless guide rod on my Gen-4 for well over a year. I like anything that puts a little more weight towards the muzzle and it’s functioned flawlessly.

  • Phil Hsueh

    I have an old (1st or 2nd gen) Glock 22 and I haven’t had any problems with the guide rod yet, granted I haven’t put all that many rounds through it either but it’s held up so far for 20+ years and a few hundred rounds.

  • CrankyFool

    I’ve had a Glock 17 since 1992, the first year I could own a handgun. In that time, I’ve fired many thousands of rounds through it, about 2000-3000 of which were done in the course of intensive 4-day handgun classes.

    The guide rod’s still original.

  • David Johnson

    Having worked a rental counter where Glocks are put through some serious abuse, I’ve never seen or heard of a guide rod breaking. I’ve seen chunks of barrel sheared off, broken locking blocks, broken takedown levers, and a back plate that cracked during operation, along with the usual parts that need replacing, but nothing with the guide rod.

    Granted, that’s not the final word there, but if anyone has ever personally seen this happen I’d like to hear about it. It’s my understanding that the guide rod really doesn’t take much force, just the spring. Even SCARs have plastic guide rods for comparison’s sake.

      Friend bought a used Glock 22. First thing he did was field strip the pistol and broke the polymer guide rod in the process(I have no idea how). I told him that Glock would replace it for free but he replaced it with a steel guide rod. Personally I think that carry guns should not be modified from the factory configuration, especially the internal parts. I also think that this was a very rare occurrence, plus we don’t know how the pistol was treated by the previous owner.

      • Al

        I bet he broke it by removing the slide, and then replacing it without pushing the guide rod back into its half moon recess, and sheared off the rear lip. That’s the only guide rod breakages I’ve ever seen with Glocks.

  • DrewN

    I put a tungsten rod (along with the grip weight) in my 34, and it made it quite a bit more newby friendly, especially being limited to 10 round mags.

  • Anonymous

    Had a customer a few months back who bought a SS guide rod for his Gen 4 26, and then discovered that the lighter recoil spring was causing trigger reset failures sometimes.

    Don’t replace something that works just fine with something that might fuck things up.

  • kaibabcoyote

    Have a Glock 27 which I recently converted to a Glock 26 with a barrel conversion and 3 Glock 26 mags. Now I have a two caliber shooter for under $200. I installed a SS guide rod from Glockmeister years ago and never had any problems shooting either caliber. I keep the original spring assembly as a spare but never needed it. The action is “sharper” with the SS guide rod. My conversion 9mm barrel was from Lone Wolf and the quality and fit is super. I like the new guide rod from Lone Wolf and will probably buy one because I can easily change springs.

    1) It is an undeniable fact the OEM plastic GRA “can” break. This breakage is a documented fact. It is irrelevant if you have personally seen this or not.
    2) The LWD stainless steel GRA “can never” break.
    3) Most Law Enforcement Agency’s replace their GRA yearly regardless of rds fired. All GRA should be replaced at 2500-3000 rds.
    4) The LWD GRA removable tip allows you to use the OEM spring weight or customize the weight to better suit your ammunition (gallery loads or +P+)
