Dry Fire Cord Glock Trigger Mod & Chamber Block (9, 40, 45, 10, 380!)

Three of the biggest challenges for dry fire training are safety, setup time, and having to rack the slide between reps.

Two of the biggest questions shooters have is how fast to run the trigger and how tight to grip.

And one of the biggest problems shooters have is low-left groups (for right handed shooters)

Now there’s an all-in-one patented solution to all of these problems called Dry Fire Cord.

Straight from North Idaho, Dry Fire Cord uses heavy-duty, reflective cord and a color-coded, quad-chamfered, anodized aircraft grade aluminum caliber specific chamber plug to make dry fire practice with your pistol safer and more effective than ever.

Dry Fire Cord will block your chamber to help prevent you from chambering a live round.

Dry Fire Cord gives you two visual indicators that the chamber is plugged.

Additionally, on all semi-auto pistols that we’ve tested, including Glock, M&P, XD, Sig, Kimber, H&K, CZ, Walther, & more, Dry Fire Cord will give you a resetting trigger for dry fire reps.

Removing The Click = Quicker Assessments & Improvement: When you press the trigger using Dry Fire Cord, there’s no click.  The trigger just goes back and forth through it’s entire range of motion.  This allows you to more accurately assess and improve how quickly you can run the trigger without disturbing sight alignment.

It makes Dry Fire Cord the ultimate diagnostic tool for shooting

No batteries to die,
no app to sync,
and the shot-calling skills that you build with Dry Fire Cord carry over 100% to live fire!

SEE exactly how firmly to grip!  A firm grip improves speed on multi-shot strings, but when you grip too firmly, your other fingers will try to join in when you’re pressing the trigger–throwing your shots to the left and low-left.  Dry Fire Cord will show you exactly how firmly you should be gripping the gun for maximum speed and accuracy.

FINALLY get the trigger control you need to fix low left groups!  Dry Fire Cord is the perfect solution for fixing low-left groups FAST.  It lets you focus on isolating trigger finger movement without the distraction of the click or bang.

Safer, more confident Dry Fire Training:  You still need to be responsible and follow all safety precautions when dry firing, but dry fire cord can help you be more confident that you won’t pick up a magazine with a live round and have a negligent discharge.

Rapid Setup and Removal:  Unlike training barrels, traditional barrel plugs, and resetting triggers, it only takes a couple of seconds to insert or remove dry fire cord.  You don’t have to disassemble it and the sharp edges of your chamber won’t scrape off shavings like what happens with some plastic dry fire devices.

Rapid Dry Fire Reps on YOUR Pistol Without Racking The Slide:  Racking the slide between reps during dry fire is a pain…and can create training scars.  With Dry Fire Cord, you can run the trigger as fast during dry fire as you do during live fire…and you’ll instantly be able to see how much your trigger press is throwing off your shot.  Want the click?  Simply tuck the tail into the magazine well and you can do traditional rack-and-click dry fire with the chamber still blocked and a visible indicator at the end of your muzzle.

Read Your Sights Better Than Ever:  When you’re working on sighted shooting, Dry Fire Cord will let you focus on reading your sights during the trigger press without the distraction of a bang, click, recoil, or trying to see where your laser hit.  This will help you avoid the “lookie-loo” training scar of trying to shift focus back and forth between your front sight and target each shot.

Gun Safe Identification:  When you have Dry Fire Cord in your pistol in your gun safe, you can instantly tell that there is no round chambered.  In addition, if you own multiple guns of different calibers from the same manufacturer, Dry Fire Cord will let you instantly identify the caliber of gun you want to grab.

Built rugged:  Dry Fire Cord went through more than 3 years of testing and 100 refinements to get to this rugged, simple, effective tool.  Every detail was thought out…from making them out of aluminum instead of plastic so that the plastic wouldn’t sluff off in your chamber, so the tolerances would be tighter, and so they’d work more reliably to the kind of cord to use to make them last the longest and be visible in your safe or gun bag in low-light conditions.

Dry Fire Cord was inspired by an instructor who showed me how to hold my slide out of battery with a piece of cardboard from an ammo box almost 20 years ago combined with a burning desire to create a safer snap cap alternative and a chamber block that actually worked and was quick & easy to use without having to disassemble the pistol.

For newer shooters, this is one more level of safety to prevent negligent discharges, to give them the confidence to dry fire more often, and help them learn to read their sights as early as possible.

For experienced shooters, now you can do dry fire training with your own gun that you weren’t able to do before without considerable cost & complexity.

Dry Fire Cord comes in 9, .40, and .45 and 9 also works in .380s.  .40 works in 10mm.

    What is the expected lifetime of a single cord? Is there a range of trigger pulls after which it needs to be replaced?

      Great question. We use 800-900 pound paracord, which is significantly more rugged than traditional 550 pound paracord for increased durability and life.

      If you ride the slide forward according to the instructions, it will last for years. Alternatively, if you’re using the .45 Dry Fire Cord in an AR-10 and letting the bolt fly forward every time, the spring is heavy enough, bolt carrier group is heavy enough, and the edges sharp enough to cut it in just a few reps–lesson: don’t let the slide/bcg fly forward.

      JUST pressing the trigger won’t cause any wear at all on the Dry Fire Cord.

    So I’m taking it that you fall on the side of no dry fire.
    While this is possible, aren’t the chances pretty dam slim?, even for someone who actually trains regularly?

      Hey Matt, I am a HUGE proponent of dry fire. I have created 15 courses on doing dry fire the right way, have a patent on 1 dry fire device, multiple patents pending on other dry fire tools, and have a few hundred articles on dry fire here.

      What is the occurrence that you’re saying is pretty darn slim?

    I do a lot of dry fire to practice. I have M&P 2.0 which has a trigger improved reset. I am hard of hearing and the click means nothing to me. So how does the dry firing cords work for someone like me?

      That’s an excellent question.

      The main purpose of Dry Fire Cord will always be to make dry fire safer by blocking the chamber and giving you a visual indication that the chamber is blocked without having to disassemble your pistol. You could still push the tail out of the ejection port as a 2nd visual indicator, or you could push it into the magwell and let the slide go forward all the way.

      As far as reasons to block the chamber, I’ll give you 3 examples of people who THOUGHT they’d cleared their firearms…


      Now the safety process that we take people through where they visually and physically confirm that the magazine well and chamber are empty make it next-to-impossible to have a negligent discharge.

      But…positively blocking the chamber in addition to properly clearing your firearm adds an additional level of safety that is incredibly important and valuable.

    Hey Lee, there’s common confusion on the “click.” In fact, your question is the most common one that we get from people after they try using Dry Fire Cord. If you’ll refer to the instructions on the card that came with your Dry Fire Cords or the instructions above, you’ll see that there’s a huge advantage to doing dry fire without the click. The trigger still resets, or articulates back and forth, but there’s no click.

    The click hides a lot of sight movement due to having too firm of a grip, an inability to isolate trigger finger movement, or trigger finger movement that is at an angle rather than straight back.

    Being able to do reps without the click will give you immediate feedback on EXACTLY how firmly you can grip the gun and EXACTLY how quickly you can run the trigger without disturbing sight alignment.

    Depending on which version of the cords you have, you may want to lightly push forward on the slide to get a little more range of motion on the trigger. We have tried 650, 800, and 900+ pound paracord for increased durability and oftentimes the 900+ pound cord will cause the slide to be further out of battery than what is ideal. Push forward a little with your thumb right after you insert the cord and you’ll be good to go.

    Just received my dry fire cords in the mail I have a model 23 Glock 40 Cal after installing the cords according to the instructions I still have to rack the slide to get a click what am I doing wrong? I tried dropping the cord into the magazine well I tried having the cord come out the side of the ejection part like it said and I still have to rack the slide to get a reset of the trigger. What am I doing wrong?

      Hey Lee,

      That’s the most common question that we get about Dry Fire Cord. In short, you don’t want a click–and that’s so out of the ordinary and different than what people expect that we understand people misunderstanding how they work. We attempt to address it in the video, in the article above, “Removing The Click = Quicker Assessments & Improvement: When you press the trigger using Dry Fire Cord, there’s no click.  The trigger just goes back and forth through it’s entire range of motion.  This allows you to more accurately assess and improve how quickly you can run the trigger without disturbing sight alignment.” (I just highlighted it) and we mention it on the instruction card that comes with the cord.

      Removing the click allows you to immediately see how firmly you can grip the pistol before it starts to cause you to move the sights as you press the trigger. Similarly, it will show you how quickly you can run the trigger before it starts causing you to move your sights.

      Sometimes, people want to feel the take-up, the wall, and a crisp reset on their trigger. I’ve got some after-market triggers and I love a good trigger as much as the next guy, but that is mostly noise in a dynamic, high speed situation…you want your grip intensity to be automatic…a conditioned response, and you want the speed that you run the trigger to be automatic as well. >>>To be clear, when I’m talking about the speed that you’re able to run the trigger, you could apply it to multi-shot sequences, but more importantly, you want to know how quickly you can press the trigger a single time without disturbing sight alignment. Ironically, the easiest way to measure and improve this is with fast strings of trigger presses using a metronome.

      I hope that helps 🙂

    I’m not able to get to ‘dryfirecords.com” that is mentioned in the video. I also tried ‘dryfirecards.com’ and ‘dryfirecord.com’ with no luck. My search engine will either not come up with the site – or come up with ‘dryfiretrainingcards’ or will give me a ‘not secure site’ and not allow visiting the site. I saw several mentions in the comments where you will be making these available, but the dates were in 2018. What is the site where I can just order the dry fire cords in the caliber I need without signing up for a program or a class?

    If I use the dry fire cord and it’s masking the trigger click and resistance of the draw stroke, will I have different results at the range than through dry fire at home?

    Thank you,

      Excellent question and I’m glad you asked it. Whether we realize it or not, we compromise on almost every aspect of shooting.

      Sometimes, it’s on purpose to break down technique and focus on the component parts.

      Other times, it’s unintentional…like practicing flat footed in low stress conditions and expecting to be able to perform well in real-world situations.

      One of the biggest problems that people have in shooting is moving the gun as they’re pressing the trigger…this is normally due to sympathetic movement of the other fingers and wrist while pressing the trigger or flinching the gun in anticipation of recoil.

      Fixing them is a combination of 4 things…

      Emotional control.
      Granular motor control that allows us to move our trigger finger independently of the rest of the fingers/wrist at higher and higher speeds while gripping firmer and firmer.
      A trigger finger that is strong enough to press a particular trigger.
      A properly sized gun for the shooter’s hand.

      Dry Fire Cord lets us break things down and isolate on independent trigger finger movement. In the process, the coordinated motor output from the brain required to move the trigger finger without moving anything else gets cleaner, more precise, and stronger.

      When you KNOW (because you’ve seen it when using Dry Fire Cord) that you can repeatedly run the trigger without disturbing the sights with dry fire cord, then when you switch to using a trigger with more resistance and a click, it’s just a matter of figuring out the perfect speed and grip firmness.

      What you want to do (and what I do) is switch back and forth between holding the slide slightly out of battery and having the additional resistance & click.

    Hi Ox, I love your training and read your emails as soon as I get them. I was wondering if it is possible to buy just one dry fire cord. As a new shooter and working on a shoe string budget I would love to buy your training package but just can’t afford it. Please let me know. Thanks for all you do.

      We’re getting there…I’ve been out of town for the last 4 days and will be shipping out orders from this weekend tomorrow. We’re assembling, packing, labeling, and mailing every single one ourselves right now, so I don’t want to sell them quicker than we can get them out. I’m meeting with a local group that helps disabled vets tomorrow or Wednesday to see if they have people who can help us get them ready in bigger quantities in a shorter amount of time. In the meantime, you can get them with Private Coaching or with the Draw Stroke Mastery system.
