With the removal of suppressors from the NFA closer than it’s ever been before, these noise cancellation devices have ironically caused a lot of noise.

Enter Fischer Development, an Austria-based company that makes a suppressor – at least for the time being -specifically for, you guessed it, another Austrian-based gun company – Glock 17 and Glock 19 model handguns.

With just one click, the Fischer Development suppressor fits on the accessory rail of the Glock, as opposed to other models that require a threaded barrel.

A few causes for concern: Glock users familiar with the firearms build may call into question how the barrel can move during recoil, as well as the actual effectiveness of suppression since the gun shoots into an “open” suppressor, instead of being threaded into the barrel.

The only other worry surrounding this suppressor is how cumbersome it appears. However, if  350 grams (12.3 ounces) is the true weight, then it’s pretty deceiving.

    1. Roughly twice the volume of some other suppressors, because it’s flat and twice as tall, but it maintains the lines of the Glock slide so it wont interfer with sight line or increase the width of the suppressed firearm the way a 1.25″ diameter tube suppressor would.

      But each to their own.

  1. As I recall, many Glocks get the ‘pignose’ problem with the rail- mine did. That +extreme wear on the rail polymer could make alignment issues, right?

  2. IF the additional volume were to somehow cancel out the open rear of the suppressor, it might be legit. I mean, if the HSA passes, I’d pay $150 for a hearing safe suppressor like this.

  3. Its pretty interesting. But considering Glocks dont usually cycle correctly when running suppressed without a booster, Im thinking this might not be as functional is it looks. Id wanna see it work effectively. IM with you evi1ljoe on the HSA.

    1. Gary – the reason Glocks don’t cycle correctly when running a suppressor is because of their delayed recoil action and the attachment of the suppressor to the barrel. That’s because the recoil needs to move both the barrel and the suppressor rather than just the barrel. By not attaching the suppressor to the barrel, the recoil doesn’t need to move anything other than the barrel as normal, so cycling should not be an issue.

      Further, since the suppressor reduce the available volume for escaping gasses as the bullet leaves the barrel, it will increase the recoil pressure on the barrel during cycling and actually act as a booster.

      1. Yeah, I understand the mechanics and the physics. I didnt realize this didnt attach to the barrel. Now IM concerned about allignment issues. Not to mention gas escaping between the silencer and the barrel. This is one of those inventions I look at and say “Cool, but I wanna see the long term reviews”

      2. Generous bore clearance, increasing as younget further from the muzzle is one way to prevent issues, which also relieves back pressure some, but at the expense of suppression levels.

        Not to forget the fact this is not sealed around the muzzle as a barrel mounted can, there will also be concern of unburned powder particles deflecting back into shooters face, but should also make it so less pressure and crap come out the ejection port.

        But alas, this leaves those of us with gen 2 frames with needing to use barrel mounted cans.

        Either way, novel concept that would make the ban on threaded barrels in some places pointless

  4. There is going to be a lot of first round pop unless they have used wipes. I also worry about how the polymer rail would hold up over time and a baffle strike maybe first sign of an issue and also the last.
