SIG MOD-X9 Selected by USSOCOM as Mk27 Handgun Suppressor

Last fall, USSOCOM selected the SIG MOD-X9 in 9mm as the suppressor for use with the Mk27 handgun, a SOF unique pistol which is known commercially as the Glock 19 and is currently in service in several variants.

The user configurable MOD-X9 Suppressor is comprised of seven, 3D-printed titanium baffles and an encapsulator with 21-points of impact adjustment.  The length is adjustable from 3.25 inches to 7.5 inches, the weight is adjustable from 5 ounces to 8 ounces, and the sound is adjustable from 127.4dB to 145.3dB.

With a handgun suppressor requirement on the books for years, the capability was finally acquired via an Other Transactional Authority acquisition which saw several manufacturers offer commercially available suppressors compatible with the Glock handgun.

Participating vendors demonstrated their suppressors to the command during a private range event in 2020. Then, they selected two suppressors to move forward with operator testing and a technical evaluation at Naval Surface Warfare Center – Crane which handles procurement of weapons for Special Operations Forces. The result was selection of the SIG MOD-X9.

Due to the nature of the procurement, traditional steps aren’t necessarily followed so unfortunately, there has been no public notice of the buy. Regardless, the first tranche of suppressors for the Mk27 handgun should be hitting units by this summer.

    Interesting that it looks like the Rugged 9mm suppressor is shown in the slide for procurement, and perhaps was between Rugged and Sig. What was the previous Mk27 suppressor the Sig is replacing? Curious that it was down selected so quickly to just two, and there weren’t more big names in the running.

      Iirc, I believe they were AAC suppressors; Tirant-9 or Evo-9 I think. I am sure someone can give a more definitive answer.

      That slide is from before the program even kicked off.

    Someone needs to teach that dude how to hold a pistol.

    Funny because that’s the last silencer I’d pick . Probably has to do with Sigg and their ability to make as many as they want faster than other company’s
