Wild Glock Mod: Windowed Glock Frame

Anibal Salinas of @Weapons_armament_research has cut a slot into his Glock grip and epoxied windows. With the use of an ETS transparent Glock magazine, he can see how many rounds are in the magazine without removing it or mentally keeping track of how many rounds he had loaded and fired.



I reached out to Anibal via email:

The Glock is still a work in progress, I should be done today with all the frame mods. The windows are epoxied and fused into place, i can squeeze the grip (without magazine) with all my strength and i cannot flex it anymore than i could stock. I plan to shoot it this weekend to put it through it’s paces but i doubt anything will happen.


Now many people will scratch their head and ask “why would you do this”? I like it. If the windows do not come loose and interfere with the function of the gun then it has practical applications. This is like a fuel gauge in your car. Do you need it? Not if you just remember how far your car can drive on a tank of gas, know how far you have driven and if worried top up. But not all of us do that do we? We are not all of the same mindset when it comes to having the same gun or using the same techniques. We are all individuals with our own unique desires and motivations.

I could see this being useful in competition. Most competitive shooters either count mentally or just say screw it, dump a partially loaded mag for a fresh one. Well here you know how many rounds are left. Also it looks cool. If nothing other than pure aesthetics it is neat to see into the gun. Sort of like why companies make cut away models of their guns.

Some will argue that the gas and gun carbon residue will coat the inside of the gun making the window obscured. Well going back to competitive shooters some of them religiously clean their gun after every match. Keep the gun clean and it won’t be an issue.

Just look at how many windowed PMAGs are out there in the world. Do they fail because there is a wndow? Does the window get dirty or somehow cause a malfunction more than a regular PMAG does? Not to my knowledge.


Kudos to Anibal for doing something different.

      That man made some cool looking guns!

    • Somebody do this with a Glock 43. ASP 2.0 here we come!

  • Julio

    I wouldn’t claim anything for the practicality of this. Comparing it to a fuel gauge is at best “creative”. I agree it looks neat, though.

    • iksnilol

      They should make a fuel gauge backplate for Glocks. As you shoot it would gradually go down.

  • iksnilol

    Reminds me of those sweetheart grips that people made in WW2.

  • Bill

    While few people can keep track of the rounds they have fired in a gunfight, I’ll bet fewer can stop, release their master grip, count rounds visible in the window, and multiply by two for double stack magazines. If it works for you, great. It does look like fantastic workmanship and execution.

    With enough practice and exposure, I think most shooters can soon intuit when they are about to run dry and reload appropriately.

    • stephen

      By the time they do all that the threat/s will have moved and put them down.


    • William Elliott

      Under stress, even practice and exposure can fail you. Back up plans are nice.
      Also, if you can’t count rounds at a glance, add marks [permenant marker?] to the outside of the window, just like they do on the Pmags

  • Rnasser Rnasser

    Practical and useful as an ashtray on a bike…

    • Evan

      An ashtray on a bike actually sounds like an awesome idea.

  • #neverbeendonebefore #industrygamechanger

  • Spencerhut

    It’s like the backyard redneck version of an ASP, but with more JB Weld. Because reasons . . .

    • William Elliott

      hey, just because its JB weld, doesn’t mean its wrong…now all it needs is a “melt job” on the slide and frame, and a See All sight in place of the Gutter sight…the new clear poly mags from ETS solve the see through magazine issue. I can dig it.

      • William Elliott

        hmmm, looking at the design…I wonder if the lexan, or whatever he
        used…might not contribute to the rigidity of the frame more than
        detract from it due to being inset and stiffer than the original

  • DW

    Someone do this mod on a Shield, a modern day ASP.

  • Joel

    Cool mod.

  • m-cameron

    I never cease to be amazed and the number of unique, creative, and innovative ways people find to ruin their perfectly good glocks.

    • Budogunner

  • aka_mythos

    I like it. My only concern is that over time a lot of clear polycarbonates and resins become foggy from abrasion.

    • William Elliott

      Hmmm, excellent point. There IS supposedly a company out there that makes lexan or plexiglass windshields for jeeps that have a coating that prevents the fogginess

      Also, even foggy, it may still work just fine…look at the above ASP. You can almost see through the frosted portion. I would be more worried about UV degredation, but I don’t think Lexan has that issue.

      • dreadnought61

        Lexan (polycarbonate) is very susceptible to uv degradation but it is very tough. Acrylic, aka plexiglas, is much more uv stable but not as tough. In the world of clear plastics everything is a compromise.

        • Justin Roney

          Yep, still waiting on transparent aluminum. 🙂

          • aka_mythos

            Yep that would solve it, but would come with a certain irony in adding “metal” to what championed the mostly plastic gun.

    • Even if foggy you can tell. I have 15 year old “smoke” butler creek mags with residue of dirty .22 ammo inside and while they are not window clear, it is easy to see how much ammo is in there.

  • politicsbyothermeans

    Without comment on the utility of this modification; I’d want to see two things before I’d consider carrying it:
    1) I want to see that thing tossed down all sorts of stairs, loaded and unloaded and then run to slidelock
    2) I want to see it function without the windows in place on the frame. Murphy gets a vote and someone will eventually have to fight without one.

    • iksnilol

      I don’t think the windows are removable. From what I understand they’re epoxied on.

      • ostiariusalpha

        PBOM means that if the epoxy fails and a window pops out, will the pistol still function as reliably as before?

        • iksnilol

          I don’t see why not. I mean, take the grips off a 1911 and see if it runs.

          Would only be more vulnerable to dirt entering.

          • Christian Hedegaard-Schou

            There’s a difference between a forged (or cast) steel frame and an injection-molded plastic frame.

            The 1911 was designed from the very beginning with those “windows” under the grips. The Glock was designed from the very beginning with a solid grip.

            There’s nothing wrong with polymer-framed guns, obviously, but that doesn’t mean you don’t compromise their integrity when you cut large holes in them that weren’t designed there by the factory.

          • iksnilol

            Eh, isn’t the frame steel reinforced?

          • BattleshipGrey

            Not on a Glock. The rails are only inserts and I’m pretty sure they don’t connect to a larger integral support system.

          • Christian Hedegaard-Schou


          • iksnilol

            That’s surprising, I know the mags have a steel frame in them.

      • politicsbyothermeans

        I once heard a staff sergeant patiently explain to a young cadet that a private could be left alone in an empty motor bay with an anvil and, one hour later, the anvil would be broken. I’ve honestly seen guys at most ranks do dumb stuff with their weapons but I’ve also seen honest stuff happen. Let’s say you’re dismounting the vehicle and your holster takes a good lick on the door of your vehicle. Does that window contribute to the rigidity of the frame and does it pop out? I hope not. I’ll bet it does eventually with repeated unintended abuse common in contemporary combat operations. And then I want to know that that pistol can function reliably, even though the amount of pistol engagements are astonishingly rare. I’m thinking about a pilot or crew on a helicopter that has crashed. The sorts of forces their equipment might be subjected to in a crash could reasonably be expected to pop the windows out…. couldn’t they? That’s when they would arguably be most reliant on their pistols. How do those see-through magazines hold up when subjected to the sorts of forces associated with a window popping out of the frame?

        Not so much questions for you, just things I’d want to know if I put this system into use tactically. I can imagine its utility in other aspects of shooting.

        • Nicholas C

          Don’t forget, gun do not have to fit in such a narrow category. They do any different things for different people. People buy them for her looks, some buy them for their mechanical uniqueness, some buy them for competition, others look at them as a tool for hard use.

          • politicsbyothermeans

            Totally agree and tried to cover my butt with that last line.

  • Justin Roney

    People thought Magpul was crazy for putting windows on Pmags too.

    • Geoff

      Yeah but windowed mags and windowed frames are 2 different beasts. It’s neat, but I wouldn’t do it until it was tested thoroughly by the manufacturer, covered by warranty, etc.

      • Justin Roney

        No reason this guy can’t try to innovate on his own if he’s willing to sacrifice his own weapon.

        With how much the polymer frames flex, I would be worried about separation between the two after time, but like you said with the resources of a manufacturer, it’s not outright impossible with enough testing.

    • stephen

      Windows on Pmags are more for admin – allows for quick check on what mag status is before you go out IMO.

      Now you will have people focusing too much on their window than putting rounds on target.

      • Justin Roney

        I doubt that. The advantage would be during a so called “lull” in the fight, when people are taught to do a magazine exchange. A quick glance would determine your need to do so. I’m not saying a full mag isn’t better, but trying to retrieve a partial mag from a pocket or dump bag later on after you’ve exhausted your full mags can be a pain. Having the option to glance at your weapon and know how close you are to a reload helps speed the process at slide lock, and dump the empty and be done with it, rather than fooling with partial mags. It basically gives you an additional option, and I don’t think that’s a bad thing. As long as it doesn’t compromise the weapon ruggedness or reliability.

  • BattleshipGrey

    I like it. I don’t think I’d do it to mine without lots of practice. BUT, I’ve been thinking about making grip panels out of clear plastic photo frames for my 92fs and make a window in a magazine.

  • I like it a lot, great modern ASP aesthetic.

    Also a great reminder that “this gun is loaded” for those who do a lot of dryfire. Quite a few people over the years have been doing dryfire practice, completed their session, reloaded, and then a few minutes later went in for a few more reps, and put a new hole in something.

  • Translucent Makarov grips would probably be the fastest route to a “modern” (my Bulgarian is dated 1991) ASP.

  • TangledThorns

    Cool, I’d like to see something like this in a smoke.

  • gunsandrockets

    how about this instead:

    Drill inspection holes in the frame, seal the holes with plastic. Less intrusive, but does the same job.

  • Aaron E

    Looks like great craftsmanship, I like it! I think it has excellent practical use for both defensive shooting and competitions.

    I don’t expect to count rounds with this window but I could very easily bring the pistol to just in front of my chest (like a reload) and conduct a quick check of roughly where I am on round count. That could help me decide to go back to the fight, perform a tactical reload, or do a combat reload.

  • Budogunner

    The comparison to Pmags is absurd. A Pmag is not a structural component.

  • Random Disabled Person

    Plus this might salvage some of the horrible dimpling jobs from Bubba and his great wood burning iron.

    Although I’m in the against corner for doing anything to the receivers because history teaches us(especially the NFA) that the receivers must be protected at all costs. Future generations may need they extra strength of that material so the weapon can be passed on in a protected grandfather clause….

  • Ripley

    How many bullets fired? Just count the bodies on the ground.

  • stephen

    Comparing it to a fuel gauge? Seriously?

    So now you’re going to have people constantly looking at their guns instead of the threats down range. I went to a carbine class and a few students were doing just that. The instructors got the ass and verbally assaulted them for concentrating more on their mag instead of placing shots where they needed to be.

    I feel the same way – a useless mod that looks cool for about 2 seconds.

  • Dave

    Clever proof of concept. I don’t think he requiring anyone else to do it, and not all guns are destined to be in death fights. Glad someone out there likes to play.

  • Arturo Suarez

    Now once ETS makes a p320 clear mag, I’m doing this and mill my slide ala Salient Arms…I think I’ll make it to Tier 1 Operator Mode.

  • itsmefool

    I cut a window into my slide and barrel so I can confirm the bullets are headed toward the muzzle; do I get a prize?

  • Andy

    “Useful in competition”….no. It’s quicker to just slap a new mag in- preferably a reliable one that would go into a frame that hasn’t been compromised. It looks cool, but please don’t try to convince me that there is any practical reason for this. Someone watched Romeo and Juliet and saw the 1911s with clear mags and grips and felt inspired.

  • Tfoxx

    Count as you shoot, problem solved.

  • Lance Shoemaker

    I believe Charlie Kelsey, the owner of DEVEL did this about the same time as the ASP.

  • They could put some texture to most of the window with just a small strip of clear and smooth. down the middle the textured portion would let light through. The part cut with a checkering file would provide better traction than the normal glock grips.

  • Shawn Wesley Knight

    This is one of the dumbest articles I have ever read. I want my 30 seconds of life back.

    This is one of the dumbest reasons to do a mod like this.
    “I could see this being useful in competition. Most competitive shooters either count mentally or just say screw it, dump a partially loaded mag for a fresh one. Well here you know how many rounds are left.”

  • Casey Gunn

    I like it. Maybe you wouldn’t need it during the first magazine. But a running gun fight? I’d like to be able to glance down and know if I need to reload.
