Glock Modifications That Should Have Never Happened

I love no-frills Glocks, but I also recognize that there is room for customization. Having said that, a man has to know his limitations. Projects like milling a slide to mount a micro red dot is functional, and when done correctly, can make the whole gun look sharp and futuristic. However, many DIY pistol modifications done today are based on aesthetics alone. Some, like those done by Blown Deadline Custom Cerakote are works of art. Others are, well, “unique”.

If you decide to take fate (and a Dremel or a soldering pen) into your own hands, make sure you do a little research first – there are hundreds of how-to guides on Youtube and internet forums. Start slow. Keep it simple. And practice on an old polymer magazine or grip before you start melting a perfectly good pistol. However, if your experiments start to go completely south, fear not. Glock, known for some of the best customer service in the business, will actually replace your entire frame or slide for around $100.

In exchange, I’m sure the good people in Smyrna will have a private chuckle at your expense.

Below are some examples of Glock customizations that fell short of perfection. Try not to laugh too hard – we’ve all been students WECSOG at some point in our lives. Besides, I’m sure they still function just fine. Ok most of them probably function just fine.


















Yes, that’s the top of the firing pin safety and spring.

I’ve always thought Glock should add portholes to some models.


I worry about the structural integrity of this slide.


EDIT: Doesn’t deserve to be on the list. Thanks for all the comments on the sight tracker from Agency Arms. My apologies.


To redeem myself, here’s a pic and a link:



Yes, bad kitty indeed.


I thought Spiderman was anti-gun?




Gandalf called, he wants his Glock back.


I actually kind of like this one.


I see where you were headed. But you missed.


Stars forward, Batman. Stars forward.


If Willy Wonka carried a Glock…


A couple of LARPers got matching pistols.


I’m sorry your cat isn’t feeling so well. We all hope he gets better soon.



I had this horrible dream last night. Glock made a carbine.


Help me out here. Is this a thing now?



Oh god, no. No! What have they done to you?

(Suck it up, M&P fanboys and girls)

    Do you shoot a gun to put it out of it’s pain? How’s that work?

    • Pete M

      Awesome. Thanks for the laugh.

      • MrEllis

        Thanks for the horror show, I’m gonna show this to my guns as a warning. Malfunction free here I come.

    • oldman

      Unless it shoots you first for doing that to a perfectly good gun. a couple of those mods seem to be somewhat less then safe but hay what do i know I tend to be conservative when it comes to modifying firearms.

  • oldman

    I have to wonder what they were thinking or if they were thinking. Oh well there the ones that have to live with it when they sober up.

  • Anonymoose

    This is why the NRA vigorously recommends against using drugs or alcohol when around firearms. They should also put a moratorium on being around firearms when hacksaws, Dremels, and heat guns are present.

    • Pete M

      Right click, save as.

      • Cymond

        I’m so sick of Disqus renaming everything “original.jpg”

        • crackedlenses

          I have a whole collection of pictures labeled “original”, “original2”, so on and so forth.

    • PK

      In that vein…

      • Austin

        Looks like it. Was made by Maliwan

  • Giolli Joker

    Stippling No.4 doesn’t look that terrible.

    The “I don’t get it” photo looks like the configuration allows to add compensation holes if needed to tune the system to your liking… It look like a subcompact Open class gun.

    • Pete M

      Yes, but the front sight on that contraption? Why?

      • Giolli Joker

        Maybe the muzzle brake is world’s oddest suppressor interface and you need a tall sight to clear it… 🙂 😛

        If you buy a short handgun and you make it 1.5″ longer with a flashlight I might already question your choices… 🙂

        • Pete M


      • Corey Evans

        To co-witness with an RMR.

    • PeterK

      All stippling looks terrible. ;p

  • Jeremy Case

    The “I don’t get it” is the Agency Arms NOC. It’s a sight tracker type set up similar to what race guns use.

    • Pete M

      So the front sight tilts up with the barrel? Why not just have a compensator? Or a longer barrel with comp cuts.

    • Giolli Joker

      Good eye…

      I fail to understand what a “sight tracker” is and what is its advantage.
      Is for the (pro) shooter to be able to reacquire the front sight faster than if it was on the slide?

      • raz-0

        It’s to minimize movement of the front sight to return to a useful sight picture faster. I say useful, because for USPSA style shooting, not every target needs a fully lined up notch and post sight picture. Sight trackers in theory help with shots that require more than having the muzzle over the a-zone and less than a fully lined up notch and post. AKA front sight only sight picture.

        • Giolli Joker


    • Pete M

      Post updated. Thanks.

  • Bill

    Professional gunsmiths love amateur gunsmiths. Job security.

  • NDS

    Actually shoot a sight-tracker style 2011 or the Agency NOC you have pictured.. You’ll “get it” in a hurry.

    The front sight doesn’t move as the slide cycles and makes for faster followups on target. Only downside is the sight radius changes as the gun cycles and that takes a little getting used to.

    • Pete M

      Thanks everyone. I’ll edit the post. I learned something today.

    • Pete M

      Post updated. Thanks.

  • Christopher89

    I’ve actually thought about buying a spare g30 slide and having it milled to look like the M&P pistols w/ Glock n Wesson engraved on the side just for fun

    • Richard

      That would be hilarious.

  • Budogunner

    What a waste of Tupperware…

  • Independent George

    I actually kind of like the scaffolding one – the “I worry about the structural integrity of this slide”.

    Maybe it’s too much, but those look like some very precise cuts and some nice beveling on the corners. It’s not a kitchen table hack job like some of the others, and I actually rather like the looks.

    • Tyler Browne

      The structural integrity should be just fine. The design is called a “truss” and is the same strength/rigidity technique often used to build bridges. I’d be more worried about reliability than anything else.

      • Drunk Possum

        Indeed, I have a slide lightened much less than that and it’s sketchy on the lockup, since the spring has to be pretty light just for the slide to reciprocate. Cool looking, but it’s gotta be dangerous.

        • Wouldn’t lightening the slide make it easier to unlock, and therefore require heavier springs?

          With a very light recoil spring, the slide velocity would be very high, probably too high for the magazine spring to keep up.

          • Drunk Possum

            I get the thinking behind that, but at least on my G34, it’s a noper.The recoil isn’t enough to compress the spring all the way and I have serious ejection issues, and that’s with a 9 lb recoil spring. Couple that light spring with the way the striker system works, and it will try to come out of battery while I’m pulling the trigger. It’s been a real thorn in my side.

  • iksnilol

    I liked the “Gandalf Glock”. It actually looks somewhat respectable.

    • Rick O’Shay

      I agree. It doesn’t look terrible. I guess it’s more a matter of taste. I personally wouldn’t carry it, but it doesn’t look poorly done.

      • Pete M

        If the frame was metal and done to match, I might agree with you guys. But the black polymer frame doesn’t do it for me.

        • Independent George

          Same with the LARPers – the designs themselves are pretty tasteful, but I’m just not a fan of the color scheme. I think they’d look great if they were actually engraved or laser etched into the slide and then refinished over it. The actual workmanship actually seems to be pretty good, too (though it’s hard to tell with the Gandalf pic). Neither are true atrocities like the cat puke, or “Bad Kitty”.

          • Anomanom

            The Gandalf is laser engraved. It’s a slide by Lone Wolf Distributors.

          • Independent George

            Thanks for the info; it’s really hard to tell with that image resolution.

      • DIR911911 .

        ahem , might shoot better with sights

        • Independent George

          They’re probably on the side of the slide…

        • Rick O’Shay

          True. I’m guessing the photo was taken by whoever did the work, before they put the sights back on?

    • Nicks87

      “Gandalf called, he wants his Glock back.”
      I agree it is kind of cool but man I laughed so hard when I read that.

    • Anomanom

      I’m not gonna lie, I like the Gandalf Glock too. It’s not just coated, it’s actually engraved, then coated. The engraved slide is by Lone Wolf Distributors, the cerakoating is by Pinstriping By Rat, where they will apparently quite happily decorate your weapon in any way you could possibly desire.

      • Pete M

        I actually own and like Lone Wolf’s gear. So I feel a little bad about that.

        But, it’s definitely not my style.

      • Pete M

        Sounds like I owe Lone Wolf and Pinstriping By Rat an apology. I’ll need to find a way to make it up to them. 😉

    • Nathan

      I did too. 🙂

    • hikerguy

      You are right. Gandalf’s Glock was the only one I did not laugh, spew, or sputter on.

      It was more like Ooooooo……Cool!

    • Agree. Browning used to have a heavily engraved “Renaissance” model of the Hi-Power.

  • Friend of Tibet

    Some people just have the worst taste…..I wonder what happened during their childhood?

  • Pete Sheppard

    I’m not a Glock fan, but some of those are just…painful…to look at.

  • Spencerhut

    DIY = Destroy It Yourself

  • salty

    lolz at the shield!!! you got me good! +2 exp points for humor

  • De Facto

    They all look equally ugly to me 😀

  • Independent George

    Shouldn’t the final image be the Sigma?

    • Pete M

      You know what, I almost did just that. I owned a first gen. Terrible.

  • Audie Bakerson

    “I thought Spiderman was anti-gun?”

    The MC2 version isn’t.

    • Giolli Joker

      Spider-Girl series? Wasn’t Peter sort of a cop?

      • Audie Bakerson


  • Michael Rice

    Oh gods, I thought HVB’s stippling was rhinestones at first. Also the pair of ‘LARPer’ pistols and ‘Gandalf’s Glock’ Actually look pretty good IMO (Gandalf looks way better though).
    As for the 4th one down on Milling, sometimes the phrase ‘Trust me I’m an engineer’ should not be trusted.

    • Pete M

      Maybe I’m just in the minority for the Gandalf Glock.

  • AirborneSoldier

    The germans used stippling like some of those pistols, on their ww2 tanks.

    • randomswede

      Zimmerit coating to prevent/hinder attachment of magnetic mines, the ridges were made before hardening to get maximum standoff distance with the least material used and weight added.

  • SirOliverHumperdink

    The one w/o the trigger guard looks like Dillinger carved it out of soap.

    • Anomanom

      More like it’s carved out of poo. Like actual poo.

  • Daniel

    I’ve got a couple Glocks that wish they were as pretty as some of those. Used case at my local shop. Sub $400 ea out the door for Gen 4 17 and 19 with nite sights. I, for one, appreciate the fact that some people will mutilate their guns and then take the laughable offers that gun shops offer them as trade on new guns. Diddy know Glocks would replace the frames. I’ll have to look into it.

    • Drunk Possum

      Diddy do know. Vote or Die, dog.

      • Daniel

        Funny. I actually got that. Autocorrect. Should have said Didn’t know.

  • John

    Every American Flag I’ve ever owned has the stars on the right if you had the pole side to the right I bet if you looked at the handle as the pole (which makes sense) the flag would be the right way. P.S. I also liked the Gandalf Glock, that one was pretty neat looking.

  • guest

    MP is like “OH LET’S ADD 10 DIFFERENT BUTTONS!!!1”

  • randomswede

    I could go for the last actual glock (you’ll have to number the pictures next time Pete, lots of “hand waving” going on here).
    If I could (and had any need to) legally carry. I’d have to try shooting pistol with a peep style rear sight, but a compensated barrel on a subcompact that can take 17 rounders for a full grip doesn’t sound like an awful idéa. Carry with 10 round magazine, have an extra 17 round magazine (or two) and keep a 33 round magazine in the car.

    I’ll go an extra step and make it a 5″ or 5.5″ barrel instead of what looks like a 4″.

    • Pete M

      You’re right on the numbering.

      Peep sight on the G26 is interesting.

    • AHill

      Looks like the G26s (minus the peep sight) we get in Canada. The extended barrel being necessary to meet the 107mm for legal pistols.

  • Jim_Macklin

    GLOCKS have a horrible record of ADs, often into the family jewels, but that GLOCK without a trigger guard should appeal to only the lowest form of trial lawyers.

    • Joe Goins

      Glocks don’t have ADs.

  • jamezb

    And one day there was comedy on TFB… and I kinda got a kick out of it, too.. 🙂

    • Pete M

      Step aside Seinfeld.

  • jamezb

    As far as “stars forward” – consider that holstered, you would want “stars top”
    – or even better “don’t paint”..

  • Peter Nissen

    I suppose it’s something “psychological” inasmuch, IF appeases the owner’s mind to make the mods and IN THEIR mind make their piece a better firearm to shoot – who am I to argue!!!!

  • Justin Roney

    The first one looks like it was attacked by a swarm of angry bees.

    I got a laugh out of the M&P picture. 🙂

  • Chase Buchanan

    Why do people want the slide to be lighter? What do people think the slide does? Why do they want it to be lighter than Glock tuned them to be?

  • dmac73

    I believe we, as firearm owners, have to keep them out of our children’s hands, unless we are training them. As all do. When you customize your firearm to look like a toy, you are straddling a thin line that I have trouble with. I am for customizing in a way that makes it yours and functions for your use. Of course any child would like to play with any firearm they see no matter what it looks like.

  • Anomanom

    Its actually the “Organic” pattern.

  • the dude

    i don’t get the last one? mp shield it isn’t modified in any way?

  • nova3930

    If you think the #2 gunsmithing tool after the BFH is a dremel, go drink some bleach

  • DChrls

    What was done to the M&P?
    I have to say I like some of these pistols. Not saying I’d do it to mine but to each their own.

  • candiduscorvus

    The LARPer pistols and the Gandalf one weren’t that bad. The rest can fry. Especially the ones where they milled the crap out of the slide. Wow.

  • cieran58

    I actually like the “finale” version– improved that glocks ergonomics and appearance.
