Taploader for Glock Pistols

I was looking into the ETA polymer glock magazines and saw them mention the Taploader. I looked it up and the Taploader is a modification for Glock slides and Glock magazines. The modification allows the slide to automatically close when you tap the magazine into the pistol.


Here is an animation showing how the mechanism works.





Here is a review that shows a little more detail of this modification.


Here is a close up of the modification.

The modification sounds like a good idea. However, is it necessary? My S&W M&P9 CORE slide closes automatically when slam a magazine into it. Which is one reason why I like shooting my M&P9 CORE in pistol matches, as it is faster than hitting a slide stop/release or puling the slide to close it. Only one of my 5 mags doesn’t do it and I don’t know why. My friend can do this with his factory Glock 35. But my Glock 35 wont and none of my other Glocks do it either. I have seen other people perform this reload with their unmodified Glocks.

One concern I have is the nub on the Glock magazine. How long will that stay on there? Obviously, it is glued onto the magazine and that is a cause for concern that it could come off and jam up inside the gun. Elite Tactical Systems Group is making transparent polymer Glock magazines and have delayed their release to make a special version that will be compatible with the Taploader.

You can purchase a modified slide by Taploader.com for $299.99. No mention of sending your own slide in for the modification.

  • I thought these things were supposed to be perfect….

    [/End Glock Troll]

    • Will

      They are, damned near, perfect if they are not modified by some shade tree gun plumber.
      But, HEY, I’m kinda partial to that “plastic” gun.

    • G0rdon_Fr33man

      Perfect in the same way a Honda Civic is the perfect car. If you want the Ferrari, you better look for an SVI, Sphinx or an X-Series Sig Sauer.

    • billyoblivion

      Perfect for what purpose?

      They were designed and intended as military/police defensive pistols based on high reliability and ease of use (simple manual of arms). IDPA didn’t exist, and IPSC was only 4 years old when Glock was officially invited to design a firearm for the Austrian Army.

      It is unlikely that Glock considered sporting/race-gun use when developing the specifications for the firearm.

      Perfection means different things in different contexts.

      That said, the notion that Glock is perfection is no sillier than the notion that HK doesn’t compromise, or any other such foolishness emanating from the sales and marketing side of international corporations.

      Or do you really thing Quality is Job One at Ford?

      Glock makes a reasonably accurate, highly reliable firearm that is reasonably priced. If you need something to carry in your belt all day every day that will stop attacks, that’s about as close to “perfect” you’re going to get this side of Plato’s cave.

  • 2wheels

    My HK does that for free 😉
    I’ve heard of plenty of handguns, mostly polymer guns, doing this. I guess it can be seen as a bonus. I’m not a huge fan, I’m used to dropping the slide myself and that’s the way I like it.
    I also don’t really like how the slide AND all your mags have to be modified for this to work.

    • Vhyrus

      I just tested all the handguns I own. My 2010 Walther P99 Night Defense in 40 WILL do it, so will my girlfriend’s 2012 Sig SP2022. My Newer P99c, PPQ, and Sig P320 will NOT do it. Since those 3 are my self defense guns while the other 2 are my ‘serious’ guns I am quite pleased with the results.

  • Or, you know, you could just buy an M&P which already does this.

    • Vitsaus

      But then you couldn’t be one of the millions of guys with the exact gun you have, doing the exact modifications you’ve done and all patting each other on the back all day about how perfect their gun is.

      • USMC03Vet

        Glock Perfection*™

        *Requires 90% of gun be replaced by aftermarket parts

        • thisguybetrollin

          Because a 1911 doesn’t ever need to be modified it’s perfect as it is and we’re stuck in the early 20th century.

          Get over yourself. The only thing my glocks need are a 15$ spring kit. BAM.

    • Grindstone50k

      Gave me a good laugh.

      My M&P doesn’t do this, but all the rentals I’ve handled did.

      • It does and it will. Stop babying the mag in there. Slam it like you’re doing a reload on the clock, and it will go. They do this right out of the box, new. Every M&P I’ve had does this stock. It’s one of the reasons I chose to switch to the M&P for IDPA. Faster reloads. S&W support will confirm this as normal behavior. So it sounds like you either ginger reload or you have a defective M&P.

        • Grindstone50k

          I don’t baby it, the slide stop isn’t worn down enough yet, and probably won’t be for a while since I don’t use it to release the slide.

          • Flounder

            It’s a technique, try inserting the mag at slightly different angles. I also found if I slammed it too hard the slide would not close. So slam that mag home but don’t try to break your gun.

    • Nicks87

      Beretta 92s do it too. I didn’t know this was a desirable feature. Just sounds lazy to me.

      • I guess you could say it’s lazy in the same way that carrying an extra magazine is lazy when you can carry loose rounds in your pocket and reload the existing magazine you have. With a tiny bit a practice this is much faster and requires less fine motor skill, which, is really helpful under less than ideal stressed conditions.

        • Nicks87

          It’s not as reliable as using the slide release or sling shot method. Ramming the magazine into the mag well, to cause the slide to come forward, can cause the top round to point up and fail to feed. I will give up speed for consistency.

          • I have 26,000 rounds through my competition M&P. One of my standard Friday afternoon drills is two rounds in each mag, I fire two shots and reload, two shots and reload, two more shots. I’ve never had the first round in the mag move or fail to feed. In fact, I’ve never had the first round come out of a dropped mag. I just went down to see how much force it would take to get that first round to pop up and so far I can’t get it to move. With a full mag there is 20lbs of upward pressure from the magazine spring. That first round isn’t going anywhere but forward.

          • Nicks87

            Sorry but I’ve seen it happen. Not just with Berettas either. But continue to do whatever makes you happy. I just don’t feel good about telling people it’s ok to use a technique that I know isn’t 100% reliable.

          • You mean like using a power stroke on a Beretta 92, when you can accidentally engage the slide mounted safety. That’s reliable…. Nothing in life is 100%, except death and taxes, so I you have to use what works.

  • Ripley

    When you wear down the contact surface of the slide release you can slam a magazine in with force and it will overcome the friction against the slide notch and the slide will drop.

  • Bal256

    A few of my handguns with high round count do that without modification. I don’t own a glock but I assumed they did the same. Maybe not enough rounds through your G35?

  • CrankyFool

    A resounding “meh”

    1. Having to modify all your slides (what, you only have one Glock?) and all your magazines strikes me as a pain in the ass;
    2. Having those nubs come off and either cause a malfunction or make you go “wait, what happened? I expected the slide to close” worries me;
    3. Having a different manual of arms between my Glock and my other handguns annoys me (though to be fair, my 1911 has a safety, so they’re already different, but pretty much all my handguns have the emergency reload look the same, and this would change that);
    4. I find that with most of my handguns I already get this basically by just keeping my thumb on the slide release as I slam the magazine in, causing the handgun to move up in my hand. If my thumb is stiff, it’ll automatically activate the slide release e voila — a loaded, ready, weapon.

  • PeterK

    Ha! Pass. Nice idea, but I have no need or desire for that particular functionality.

  • Samson

    I have a Gen 3 G23 and it does this too. Now granted I would call it “slamming the mag home” rather than tapping it, but yeah, if the slide is locked back, and I insert a new magazine with some real sportiness, the slide will close and chamber a round automatically. And the idea of buying a whole modification for a Glock or whatever, a new slide and mag etc. just for this, is ridiculous. Total ridiculous. Whoever told this guy “YEAH! PEOPLE WILL BUY THAT! YOU’LL BE RICH BEYOND YOUR DREAMS!” should really be tarred and feathered.

    • nadnerbus

      My gen 2 G19 has done the same thing since the day I bought it. Whack the bottom of the magazine into the grip with any authority, and the slide snaps home. I never liked it. A gun shouldn’t do something you don’t explicitly intend it to do.

  • Squirreltakular

    * Insert standard reply about moving parts, failure points, manual of arms, muscle memory, etc…

  • How to obtain the best Glock possible:
    1. Buy Glock
    2. Done

    • Machinegunnertim

      Back in 1982 that would have been a correct statement.

  • Grindstone50k

    I want somebody to build a Glock with as many aftermarket tacticool bullsh!t as possible and show us the results.

    • That would be the Timberwolf Glock. You can build a Glock without a single Glock part. Or, you can go to any IPSC/USPSA match and look at the open guns.

  • joshuasheadinass

    Are you trying to say that glocks AREN’T just fine without replacing 90% of the components with aftermarket products?

    Or are you saying that 1911’s are keeping up with today’s technology?

    Whatever you’re trying to say with your comment, it is probably wrong.

  • Nathan Means

    Any glock I have shot will do this with no modification. They do need a couple boxes of ammo to losen things up first. I cant think of a single pistol I have shot so far that woul. not do this with enough of a slap

  • Flounder

    Guys… Almost all semi auto pistols do this without modification. My 226 does this my FNX does this Both M&P’s do this (they are the easiest and most forgiving). It is how you insert the mag. Double stacks are easier than single stacks and full sizes are easier than compacts.

    So if you have a single stack compact this would be nice… But otherwise it is just a skill that should be learned.

  • billyoblivion

    If you can’t shoot a glock moderately well, it’s not the gun that’s the problem.

    • iksnilol

      Oh no, I can shoot it reasonably well. It is just a mediocre handgun that is way too expensive for what you get. I can buy a CZ 85B for exactly the same money I can get a Glock 19.

      If a new Glock cost as much as the used police trade ins go for, then it would have been a good value gun. As is? Too little bang for your buck.

      Besides, Glocks aren’t made for accuracy (, in Norway you can only buy pistols as comp guns) and at least (here in Norway) it is mostly the mall ninjas or wannabe commandos that use them “Because that’s what some branch of them military uses”.

  • LouisCQ

    Sounds like a solution in search of a problem.

  • iksnilol

    If I use them for the same purpose, that is:

    -accurate shooting
    -occasional CC

    Then the Glock is mediocre. Sure, it is lightweight, but so is a NAA Mini Revolver. Yet, nobody touts that as perfection. Sure, if you have some nerve damage or something then I can see why you’d carry a polymer pistol.

    Why should weather give me problems? Is the cold steel frame gonna mess up my shooting? Is it gonna hurt me? There’s a reason I wear fingerless gloves (even during the Norwegian winter, so don’t tell me it can’t be done).

    Now I am not saying you can’t kill somebody with a Glock, because that’s what it was designed for. It was made as a simple pistol you only drew when you were going to shoot somebody, especially useful for people not trained too well (thus no safety). Just that there’s more bang for your buck in other pistols.

  • Sledgecrowbar

    You can pay for this? Mine does this if I load it hard enough, which isn’t very hard, but I think it works slightly better after it’s warmed up, too. I do like it, but it’s never failed to strip a round, either. That’s probably the main thing that would make me hesitate doing it. As long as it’s been tested as much as all the other stuff on Glocks, fine.

  • guest

    Sorry to burst the bubble of both the designer of this yet another “solution in search of a problem” and some fanboys of cheaper glock-alike copies who boast their guns have this feature already. But the fact is factory Glocks will do this out of the box with standard magazines!

    For those that insert new mags like their insert their willie on the first night to get their cherry popped, here’s some advice: when slide locks back on last round, after ejecting empty mag take the fresh full mag and in one firm and confident motion slap the full one right into the gun. Not just shove, slap it in like you mean it. The shooting hand must however remain stationary and so should the gun. Chances are the slide will release itself. If not, try and try again. There may be some more choreography involved, tilting the muzzle slightly down may help. I can do this with the gun relatively immobile. In the long run this can be repeated reliably and easily.

    The only “downside” is that this is not an actual intended mechanical function, but a combination of relatively light lower frame, heavy slide, and a slight forward motion of the frame relative to the slide due to the almost diagonal motion of the new magazine entering the mag well and as it stops that momentum translates to a slight forward push that is enough for that tiny frictional surface between the stamped mag catch and the slide’s mag catch cutout to disengage mutually.
    Can be mechanically improved upon by gradually and very carefully filing the slide catch notch in the slide until the slide will release if someone coughs too hard in the room. But again – this will work on any factory Glock with no modifications what so ever.
