Live Fire Test of Fischer Development Glock QD Suppressor

Remember the Fischer Development QD suppressor for the Glock? Erik B. posted an article about it back in March. Click here to refresh your memory.

Fischer Development has posted a video of a live fire test. Ignore the tactical masturbation at the beginning. The concept is rather interesting. The suppressor attaches to the accessory rail of the Glock. I am still skeptical of how well it can seal the the gas and pressure since there is a gap between the barrel and the suppressor. I think it would not work well like suppressing a revolver. Other than certain revolvers like the Nagant revolver, most revolvers have cylinder gap. This defeats the use of a suppressor. I also have issue with the shooter installing the suppressor while the Glock was loaded and chambered. His had is in front of the muzzle of a loaded weapon.


Another issue is in this screenshot. You can see the gasses escaping out the front of the suppressor. However look at the bottom. Gas is also leaking out the bottom of the can. I am not sure if that is supposed to happen.

I hope these are imported or made under license in the US. I would like to see how effective they are compared to traditional pistol suppressors.

    that must have a hella large bore to keep baffle strikes from happening. That accessory rail is meant for flashlights, not suppressors. I can’t imagine the POI shift just between shots. I can move my glock dustcover back and forth, up and down just with hand pressure

    • PK

      That was my first thought, as well. That’s a baffle strike waiting to happen!

    • randomswede

      It could be that the system is adjustable and preloads. A thread on suppressor of course goes on with (probably a couple of magnitudes) more force, but perhaps they still have sufficient force for repeatability.

      Well, if they are selling it to people who bet their life on the suppressor they better know what they are doing.

    • Gary Kirk

      Looks like it may brace against the trigger guard, and the rear section is probably aluminum, which could stiffen the dust cover some.. But, I’m not gonna try it..

  • Duray

    Or just use a Silencerco Maxim 9.

    • drambus

      Or the Fischer suppressor for the range and maybe glove box, detatch the suppressor for IWB carry.

      I like options, and I know the Maxim has an adjustable can size, it’s just more conspicuous since you can never fully remove it.

  • PK

    Think about the overall construction: bolted on sides, attached to the dust cover/accessory rail, it’s going to have a very large bore and leak gas everywhere. I’m sure it works, to a point, but I’m certain that there’s no reason to go with this system in a country where you can get a drop-in threaded barrel easily.

  • Nooky

    Let me just put my hand in front of a loaded gun.

    • Ehtacs

      I noticed that when I first saw these photos but even conventional suppressors require a hand in front of the muzzle. If anything, this unit could be held by the bottom when it gets clipped in instead of threaded on.

    • Oregon213

      And a glass-breaker mag basepad…..

  • Action45

    I cringed when he mounted that thing on a loaded chamber…day 1 stuff dude.

    • Especially since it could just as easily have been mounted from underneath without flagging himself.

  • So what are they going to do when Glock changes out worn out molds? I’m sure Glock does not keep the rail to 3 decimal tolerances. So then they are going to have a suppressor for each mold code? For those that do not know, plastic molds typically have a code some where on them to tell the manufacturer which one the item came out of. Then you have to think about long term loads on a piece of plastic with no metal reinforcement. Each time the gun is fired there is an eccentric load on that extension of the receiver and over time it will slowly deflect. And as pointed out, I’m sure it sound like garbage since the gap between barrel and suppressor is there as well as the extra generous bore.

    • PK

      Mold changes and tolerance issues… oh, I know! They’ll just make the bore 0.750″, problem solved! /s

  • mrpotatocat

    This looks cool, very Si-Fi. That being said, it seems to be a very poor design and an accident waiting to happen. Baffle strikes or NDs…

  • Blake

    You can also see gas escaping the rear of the suppressor in the screenshot. This seems like a massively inefficient design, but living in Kommieforniastan I am very ignorant of suppressor specifics. How hard is it to suppress a pistol? Maybe even though this is a really inefficient design it still gets the pistol down to hearing-safe levels.

  • BenJamin

    Here’s my take on this: This is still a prototype, and I’m sure marketing put pressure on engineering to show a working concept just to keep enough interest in this project. I’m sure they’re quite aware of the gasses escaping the four corners of the can and may have plans for an extruded aluminum housing similar to the Osprey. Looking at the front of the can, the bore hole looks greater than 9mm, so they may have a larger diameter to prevent baffle strikes, similar to the Dead Air Wolverine. As for the seal between the can and the barrel, they may have a proprietary o-ring adapter that they removed in the closeup in the video, so no one can guess how it seals.
    This may be a novel product, or it may be a hyped up piece of garbage, waiting on later prototypes to decide.

  • mustridemore

    So, being as this thing is not mounted to the muzzle,is it still an NFA item?

    • Does it reduce the sound of a firearm’s discharge by as much as or greater than 1dB?

      Then yes.

      • iksnilol

        Wouldn’t sound traps then be suppressors? (sound traps are those barrels with insulation inside that you shoot through, common in Switzerland amongst others).

        • Steve Truffer

          No, the NFA specifies a “portable device designed to muffle or disguise the report of a portable firearm. This category does not include non-portable devices, such as sound traps used by gunsmiths in their shops which are large and usually bolted to the floor.”

    • Duray

      Being attached to the muzzle has nothing to do with being an NFA item.

  • mazkact

    Why don’t we attach a suppressor to a flimsy plastic rail …………….and THIS
    “I also have issue with the shooter installing the suppressor while the Glock was loaded and chambered. His had is in front of the muzzle of a loaded weapon”. Cringe worthy that.

  • steve

    wouldn’t it be far easier to just make a glock/pistol barrel with a different attachment mechanism besides threads if the goal is a QD silencer?
    I get that the advantage of this is that you can use it on any glock, but I can’t help but think the type of people who would carry a silencer with them in some sort of “tactical scenario” wouldnt consider it a huge deal to have/get a barrel with some kind of attachment system. I also can’t imagine there are a huge number of scenarios where anyone would need to quickly attach a silencer(with the possible exception of serving a warrant and all of a sudden discovering that it’s a meth lab.)

    • Wow!

      Actually that is the purpose of these kind of silencers. It is for law enforcement who may need suppressed capabilities either because the neighborhood they are in or whatever. It is cheaper to have several of these silencers kicking around that anyone can throw onto their weapon if needed, than to purchase new barrels for every single handgun in inventory.

      If I recall correctly, I think Glock made some disposable silencers but personally I have only seen one in person, and that was in a south asian country.

    Is it their aim to turn all guns to look like buck rogers, pa chew pa chew

  • Squirreltakular

    Attaching a spinning dildo to the bayonet lug is new and interesting. Let’s do that.

    • Shawn

      go for it buddy. I’m not sure how new that would be though.

  • Colonel K

    Narrator must be from southern Austria.

  • Wow!

    Criticism is fine. No one should support a company or product just because it is novelty. If the product does work as advertised, they will be purchased regardless what anyone says. The people with most buying power in the combat related markets generally focus on pragmatics over just innovation.
