Glock Magazine Floorplate / Glass Breaker

DPM Floorplate - 660x430

DPM Systems Technologies Ltd. is a firearm accessories manufacturer from Athens, Greece. They are mainly specialized in making recoil reduction systems for rifles and pistols. They also manufacture Glock replacement magazine floorplate, which has an integral carbide tip working as a glass breaker.

DPM Floorplate -5

It is a drop-in accessory and simply replaces the factory floorplate. DPM Systems floorplates are made of polymer or aluminum and come in two different sizes. One size fits 9mm, .40S&W and .357 SIG chambered Glock magazines, and the other size fits .45ACP magazines. The aluminum version is offered only in black color, but the polymer one comes in four color options: black, desert tan, OD green and yellow.

Here is a video from manufacturer’s YouTube channel showing how the glass breaker works:

The US division (DPM Systems USA) of the manufacturer has only the polymer version of these floorplates listed. Regardless of size and color, they are priced at $34. The original Greek website has the aluminum version at €38, which is roughly equal to $40.5.

Using these floorplates as a glass breaker looks to be relatively intuitive and convenient. However, I guess tapping the magazine to seat it in place and at the same time having this floorplate installed can be a pretty painful experience for your palm.

    Do they work on ceilings? Cuz I hear those are tough.

  • kajsnb

    This is really useful.
    Need to borrow someones car? Break the window
    In a car you need to quickly get out of or shoot out of? Break the window
    Or if Point Break style your on the run or chasing some baddie, you can go through glass. No need to shoot.
    Although there should be one that mounts on the front.
    Also it’s probable it also breaks skulls, slightly less lethal option.

    • DIR911911 .

      breaking the skull is quite lethal

    • Brick

      Nah, Johnny Utah is a SIG man. Ha ha.

  • Harry’s Holsters

    My understanding is these are useless on cars made after a certain year at least here in the US.

    Safety requirements have a new coating that makes these ineffective. I think I saw this on a practically tactical interview.

    • Phillip Cooper

      I don’t see what use a coating would be against a hardened steel point-loaded spring aka centerpunch.

      • Twilight sparkle

        I find those things rather handy for staking sub par ar builds… After you torque the stock to correct specs

      • Nashvone

        Much like the windshields, the reinforced side windows won’t come apart after they break. It’ll splinter but the purpose is to keep the occupants in the car in an accident.

      • Harry’s Holsters

        Not saying it won’t damage the glass. It just won’t have the effect we all imagine. In reality it’s a shattered piece of glass that is still together and requires a lot of work to break through.

        • Phillip Cooper

          side windows are tempered. Front are laminated. A center punch WILL shatter tempered glass.

    • Mystick

      Glass is glass. They haven’t worked out transparent aluminum yet… beyond sapphire.

      • Swarf

        Glass is glass, but what is between two sheets of glass isn’t.

        Also, glass is glass, but tempering is science.

        • Mystick

          It’s still glass.

      • Actually they worked it out enough to obtain a patent for it in 1993; it’s called aluminium oxynitride and it’s already used commercially to make armor glass that can stop .50BMG, so I’m pretty sure AlON would pull this dumb gimmick’s pants over its head and steal its lunch money.

        • Mystick

          Huh…. I did not know that.

    • It’s not the coating that makes auto glass tough, it’s the layer of plastic laminated between the inner and outer layers of tempered– i.e., “really freakin’ strong”– glass. The exterior coating does make it much more scratch resistant and more likely to make a gimmick like this skip off, though.

  • Will

    How many people will actually remove the magazine from the pistol before using it to break glass? The pounding will LIKELY dislodge rounds from the magazine itself.
    Leaving it in the pistol is a sure step toward a negligent discharge. By the way just shooting the glass would probably break it.
    A $7.00 spring loaded center punch, carried in the glove box, makes short work of automotive glass.
    Just my opinion.

  • DGR

    Wearing my “gunfight-focused end user” flip-flops to the range just keeps getting more and more dangerous…

    • Billy Jack

      You need tactical flip flop laces. Think Roman sandals with paracord.

  • DIR911911 .

    looks like a good way to split someone’s skull open if you had to resort to hand to hand . . . or were a bad cop

  • Sunshine_Shooter

    #1 Seating mags in my gun.
    => non-starter
    #2 Swinging my gun around in public, flagging myself and others as SOP
    => non-starter
    #3 Smashing my gun into hard objects as SOP
    => non starter
    #4 “just use a backup mag” => why not use a different object entirely?

    Rating: I give it 5 derps out of 5.

    • Phillip Cooper

      Use an automatic center punch… you know, like the Fire department (and thieves everywhere) already do.

      Also, why on earth would you ever have need to break glass and have your weapon out? Mall ninja game is strong with this one. It ought to come with a CWP Badge and holder as well, maybe even a set of handcuffs.

      • DIR911911 .

        tactical vehicular entry

  • Anomanom

    Tactical pistol-whipping tool. See movie Equilibrium for example. Breaking glass? I already have a tool for that. It’s called a rock.

    • Mazryonh

      Interesting that someone here remembered those “magazine baseplate studs” on the Grammaton Cleric pistols from that movie.

      But auto glass is generally tough enough to require a more specialized tool than just a baseball-sized rock to break in one blow. That’s why you see glassbreakers on everything from survival knives to flashlight battery caps now.

    • bababab

      Due to a child being stuck in there I had to break a window with a rock once and it was quite difficult. (above average strength) Virtually impossible from inside the car (assuming you had a rock). Your average folding also wouldn’t do squat.
      Gluing a centrepunch to your pistol isn’t a good alternative. And carrying a auto centre punch is also a hassle.

      • Mazryonh

        “Your average folding”? Do you mean “your average folding knife with a glass breaker”?

  • MrBrassporkchop

    This is lame. I already have a glass breaker. It’s called my fist. What Glock needs is a gauze dispenser floorplate.

    • CommonSense23

      I would love to see you break a car window with your fist.

      • Phillip Cooper

        Congrats. You’ve sussed out why he needs a gauze dispenser, all on your own… 🙂

        • Mystick

          Did you give him his banana sticker for the achievement?

        • I think CS23 was probably referring to the fact that it is actually really super hard to punch out a car window. I mean, I’ve done it– by accident, because the rubber cushion on the door had deteriorated away so it was glass on metal– but auto glass is designed to be tough and a fist spreads the impact out too much to be effective most of the time.

          • iksnilol

            I broke a window with my fist, but not a car window. Doubt I could do that.

  • AK

    Could be a useful tool, but quite “niche”. Maybe a good option for a beat cop on a backup mag for car crash scenarios or emergency entry in a house, etc. Would negate the need to carry a separate tool, reducing overall weight on belt.

    • Twilight sparkle

      Do you know how light center punches are? They’re probably lighter than this thing and you can stick it in a pocket with your pins

      • AK

        True. But the extra mag will always be on that belt, while most people I know don’t carry a center punch regularly.

        • Twilight sparkle

          This thing is still going to be a big flop, if you carry it as a spare mag then mag changes will become extra panful. I thought tomorrow was April 1st instead of thanksgiving when I saw the article to be honest.

          • AK

            If it’s in your second spare mag, your police department would be in quite a warzone for you to regularly having to slap that puppy in your pistol in a hurry…and your palm is soft and not made of glass, so the nub will just tickle a little.

          • Twilight sparkle

            My family is waco pd and Waco is pretty crazy… Though there aren’t as many shootouts as the media makes it out to be; however, cops carry a lot of things that are perfectly capable of breaking glass without an unknown quality that could cause feed issues in their duty handguns.

        • The Forty ‘Twa

          A lot of cops will though!

          • AK

            And a lot of cops will forget. I agree this is a bit gimmicky, but it’s an option, especially if standard-issued for a department as a whole.

        • Phillip Cooper

          Clearly you don’t know a lot of cops, EMS, fire rescue, or car thieves.

          Onya for not knowing many of the latter.

        • Anomanom

          True, but most if not all cops carry some variety of truncheon, whether collapsible or solid. Perfectly adequate for smashing a window if the situation calls for it.

    • It would almost certainly be simpler/easier to just go Inspector Zenigata on a window by hitting it with spinning handcuffs.

    So glad to see this! My jackets weren’t having holes abraded in them fast enough using regular magazines!

  • BearSlayer338

    What a silly idea.
    I think you are more likely to scrape your hand good trying to do a fast draw with that glass breaker than actually needing the thing. If for some reason I need to break some glass I’ll just use my multitool,besides just being able to break things it has some tools that come in handy.

  • Nocternus

    Just mentioned these to a group of Sheriff’s Officers I work with and they all thought it was a really interesting idea. Price seems right. I like the yellow ones on your second backup mag as a window breaker that is easily identifiable and always with you. Not sure why these are getting so much hate on here.

  • DaveP.

    Wanna break windows with a Glock? Go look at a Taylor Freelance Seattle Slug: a big lump of solid brass that plugs into your frame and acts as a combo frame weight and headbuster.

    • Mazryonh

      Glass breakers use a specific kind of metal in the tip to instantly shatter automobile glass. I don’t think the gadget you mentioned has that kind of metal tip. Besides, it appears to fit into the hole behind the magazine well, and the way you have to angle your hand while swinging it down on something to make it the main striking point is awkward and possibly dangerous for your wrist, assuming you’re holding the handgun in the same way you would do to fire it conventionally.

  • Mazryonh

    Somehow I think Law Enforcement customers aren’t likely to buy these. There would probably be accusations of police brutality if an officer had to pistol-whip someone with this “skullcracker” on the baseplate (never mind that hitting someone in the head with an unmodified handgun’s butt is perfectly capable of breaking skulls on its own). Besides, you can get automobile glass breakers on other police tools like collapsible batons, multi-tools, or even flashlights.

    This does remind me, however, of similar spiked “standoff devices” used to cover the muzzle ends of semiautomatic handguns so they remain capable of firing even when pressed right up against, something which would normally push the slide out of battery most of the time. Those devices also happen to turn a handgun into a more effective punching implement as well.

    • Yeah, an LEO almost certainly would have something far more practical on that fifteen pound duty belt for breaking glass, like cuffs, a flashlight, a radio, pepper spray, a baton, three pounds of keys, a knife…

  • Swarf

    That’s so Raven Glock.

  • Goody

    Or y’know just carry a knife…

    • Mazryonh

      Because after you break the glass, you might just have to cut a problematic seatbelt . . .

      • Goody

        It’s not just that, for busy people a carried knife comes in handy several times a day. Even tasks as innocuous as pointing out small details, like showing a split case neck to a novice shooter, they are just a good tool to have. Some come with carbide breakers, but I doubt that auto glass would hold up to the steel point striking an edge.

        • Mazryonh

          You could just pick up a multitool instead. Some models have both knives and carbide-tipped glass breakers, as well as the usual assortment of tools. Or even just a small laser pointer so you don’t have to point out small details by physically touching them with a tool.

  • 🐒👊
  • Bill

    Obtain spring-loaded center punch, high-visibility cord, and heat-shrink tubing sized appropriately to center punch.

    Use tubing to secure loop of cord, length of your preference, to center punch. Hang center punch from car headrest, battle bag, whatever, along with seatbelt cutter.

  • M1911

    Ok, you got me there.
