Strike Industries’ New G4 Slidecomp For Gen 4 Glocks

Strike Industries is at it again with their new G4 Slidecomp Glock compensator that requires nothing other than you owning a 9mm Gen 4 gun. That’s right, no threaded barrel, no expensive porting, just a stock Gen 4 Glock in 9mm. So why is this exciting? Well, if you haven’t shot a comped gun, there isn’t much that is quite like it in terms of getting the gun back on target quickly.

Before we go any further, THIS WILL NOT FIT A GEN 3 GLOCK.

If you are a gamer or just like dumping rounds onto a target as fast as humanly possible but don’t have a need or want for a threaded barrel the G4 is just about the only option I am aware of. It seems like the comp attached to the slide by a plug that is inserted through the nose of the slide and retains the comp with some dimples and set screws. Since the comp attaches to the slide Strike reports that you can use it to cock the gun by driving it into a hard surface (in a safe direction of course.) I am a bit puzzled by the use of a Gen 3 recoil spring assembly, I assume that is to make room for the plug.   Package includes:
– 1x G4 SlideComp
– 4x M5 Installation set screw (side)
– 2x M4 installation set screw (bottom)
– 1x 2mm Allen wrench
– 1x Glock gen 3 guide rod and spring

– Eliminates the need for threaded barrels
– Blended, no snag profile
– Precision CNC machined
– No permanent modification of weapon required
– Compatible with fourth generation G17, G19, G22, G23, G31, G32
– Compatible with open-bottomed holsters

Pre-orders are open now, no word on the ship date on their page. With an MSRP of $79.95 the G4 Slidecomp is a touch cheaper than other comps on the market and not needing a new barrel makes it even cheaper. Learn more about it on the Stike Industries website.

    The price is right, IMO. I’d wait for an honest review of it’s actual performance, though. And I want to see that it remains reliable.

    Last week, SI put out a teaser youtube just featuring slo-mo firing of it:

    • Giolli Joker

      Needs more Glock 18.

    • Phillip Cooper

      I’d like to see the same shooter/identical gun without the comp….

    • Sianmink

      Not one to ride the reset, is he?

      • koolhed

        I’m not even sure he’s an operator.

    • MadMonkey

      Am I the only one who thought he was shooting a stock Glock at first? I don’t see much if any change.

  • Bigbigpoopi

    >This comps hates the Gen 3
    >Timberwolf frames hate the Gen 4
    I’m done with Glox.

    • Jared Vynn

      Just wait for the P320 third party market to explode.

      • Sunshine_Shooter

        Which it absolutely will, thanks to the Army’s adoption of it.

  • thedonn007

    It cannot be very efficient if the barrel has to pass through it.

    • Theo Braunohler

      Good thing it doesn’t, then.

      • thedonn007

        If it is slide mounted, the barrel will have to pass through the brake, otherwise very bad things will happen.

      • raz-0

        The barrel passes through it in recoil. It’s mounted to the slide which reciprocates. Watch the video posted int eh comments. You cna see the barrel poke out the front. That’s why it has that stupid ass U hogged out the front, to allow for the barrel to tilt.

  • Corwin Bos

    Completely unnecessary unless you are feeding the gun a heavy diet of +P ammo or handload to 9mm Major. I like Strike Industries as a company, but this is nothing but pandering to the no-nothings to sell them something they dont need.

    • Joby

      If they made a one in the larger calibers I would love this on a G40. An extra longslide 10mm is something I haven’t realized I wanted until now.

      • Corwin Bos

        On a 40 with standard velocity loads, not needed. +P and Major loads, yes, its a sound investment. On a 10mm with full power loads, it would be good for some people, but I dont find the 10mm to be that bad that I cant keep it on target for follow up shots.

    • Sunshine_Shooter

      I think you are looking at this the wrong way. It’s not that no one who doesn’t shoot +P would need it, but that more people *can* shoot +P and shoot it better.

  • Phillip Cooper

    Man, this is serendipity…. I just bought a G4 G23 and was going to throw a comp on it to make a Roland Special. This makes it a heck of a lot cheaper!

  • Brad Nims

    I want this in .45 ACP so I can put it on a G41. I like the looks but don’t expect any noticeable impact on performance.

  • gunsandrockets

    Just the thing for a Glock 32?

    • Sunshine_Shooter

      Noice. I’d run it.

  • Harry’s Holsters

    Looks interesting but I’m a little skeptical of the mounting system. Does it mount through the front of the slide and then the guide rod goes in behind it?

    Also that’s one of the weakest points on a glock slide. I want to see a torture test. If the system is durable great but I see potential for breakage.

  • USMC03Vet

    Guess who’s going as John Wick this Halloween.

  • Christian Hedegaard-Schou

    Uh, the only reason this comp will work is the fact that it’s a big weight on the end of the gun.

    It’s going to be about as worthless as barrel bushing comps for 1911’s. If the barrel has to pass through the comp (which, the way this thing is designed, it does), then the bore diameter is WAY too large for their to be any actual real braking effect as the gases just pass around the bullet, instead of getting directed upwards.

    I guess it looks neat though.

  • BattleshipGrey

    Finally someone came out with a Glock comp that actually plays into the Glock’s contours. I don’t do any competitions with my pistols yet (none around me) but when I was looking into .460 Rowland there were no comps available that really felt like they matched the gun. I know this isn’t in .45″ in yet, but maybe they’ll expand.

  • Pumpkin King XXIII

    Why come out with a 4? There has to be 100s of thousands more 1,2&3 out there.

    • Blake

      Seems pretty obvious that they were only able to do a 4 because of the way the recoil spring and dust cover are designed.

      • Pumpkin King XXIII

        It’s not that obvious the kit includes a 3rd gen recoil spring and guide rod.

        • DonDrapersAcidTrip

          What does that have to do with what he said? A gen 4 has the bigger hole at the front of slide but obviously the 4’s recoil spring isn’t going to be usable with this.

          • Pumpkin King XXIII

            He said it had to do with the way 4 the generation recoil spring and dust covers are designed. If the replace the original recoil spring then it has a zero relivence to the recoil spring.
            At that point the only relivence is in fact the dust cover hole is larger,
            Therefor if they wanted they could make a 2 piece guild rod/recoil spring system like the SGS beretta design for the 1-3. This makes more sense since there is probably 8x more 1-3 than 4 generation.

          • DonDrapersAcidTrip

            “If the replace the original recoil spring then it has a zero relivence to the recoil spring. ”


  • paltik

    it will put a lot of stress at the slides end it will crack in no time….

  • Sunshine_Shooter

    Does it take Glock mags? Also, can I 80’s-style hip fire it?
