B&T AG’s Glock 42/SIG P238 Suppressor

2014-12-19 03_29_54-Impuls-380A Pistol Sound Suppressor with Barrels for Glock 42 and SIG P238 - You

B&T AG (formerly Brügger & Thomet AG) of Switzerland have introduced a new sound suppressor targeted at the .380 subcompact market. The suppressor is partnered with a barrel either for a Glock 42 or a SIG P238 pistol. Designed to be smaller than other suppressors, it still offers hearing-safe sound suppression of about 28db (about the same as a pair of ear plugs). B&T has released through their YouTube channel a brief, but satisfying video of the new product:

A unique extruded hexagon-shaped wrench is used to replace a rubber wipe at the end of the suppressor, a design feature presumably included to reduce the size of the can as much as possible. Specifications are below:

    Next Mossad’s tool?
    Interesting video and product!
    Apparently the Glock owner can operate faster! 🙂
    (the Sig owner operates with more class)

      I was thinking exactly that: What a great platform for.. er… “discrete social work”.

    Nice European product. Wipes are a no go in the US market because an owner would have to send it back to the mfg for servicing.

    • Ethan

      Why are wipes a no-no? There are numerous designs in the US that have an option to use wipes.

      • Matthew Brennan

        Think of wipes as a sacrificial baffle. They are only good for a limited number of shots and then must be replaced.

        It is my understanding that the BATFandreallybigFires has declared wipes to be “suppressor parts” thus a “suppressor” requiring SOT 2 replacement/manufacture.

        In Europe, generally, suppressors are not regulated the same, making the use of wipes more practical.

          Very Interesting… I had heard the opposite, though not from any official source. I’m curious if anyone has s link to the ATF ruling on wipes..

    Meh, a not super effective supressor for a very not effective round. And at that point you are negating the small size of the handgun, so why not step up to a round that is worth a damn at that point?

    • Ethan

      It think it focuses on being really quiet, very portable (for a suppressed pistol), and moderately concealable all while still poking much bigger holes than a 22LR.

      – 380 is naturally sub-sonic (unlike most 9mm). Good news for suppressed work.
      – Its a common round that expanding HP’s are readily available for
      – When assembled its still compact enough to be about as concealable as a full size duty pistol, but with a shorter grip.

      Basically, think of it as a suppressed 22 pistol that throws expanding Ø.355″ slugs.

    I’m a really big fan of minimalist suppressors. Unless bleeding edge silence is your absolute top priority, is it really worth an extra 3″ of length to achieve that last 8-10% boost in performance?

  • It’s a wipe. It helps reduce decibel levels without increasing length or size, but the wipes have to be replaced regularly.

  • I do not know; probably depends on the wipe.

    • It depends upon the projectiles used too. Round nose bullets are friendlier to wipes than flat noses and JHP.

        I wonder if firing a JHP as first shot through a wipe would clog it with rubber, like it happens on many JHPs on denim test.
