SILENCER SATURDAY #163: Innovative Arms 9SX Pistol Suppressor

by Pete

Good evening everyone and welcome back to another Silencer Saturday brought to you by Yankee Hill Machine, manufacturers of the YHM R9 multi-caliber suppressor. Last week we got a look at the Bowers VERS 9S subgun suppressor. This week we get a quick run through of the Innovative Arms 9SX pistol suppressor. How does it stack up? Follow me for a lightning review.

I am a winter fan at heart, but snow and bitter cold is terrible for both the shooting sports and photography. We’ve got about a month before everything starts to thaw, but my apologies for the anemic coverage. I promise you that we have some solid reviews coming when warmer weather hits.

Pistol Suppressors @TFB:

Forget our previous discussions about whether or not pistol suppressors are worth the the time and effort, (let’s say that they are). When it comes to materials, internal design and features, the options are pretty simple.

Aluminum or Steel?

For me, the weight savings of aluminum is going to beat out steel for a pistol silencer. The lever forces pulling down on that muzzle are going to be a lot worse with each ounce added. Yes, you are going to have a limited amount of cleaning options, but I think it’s a worthwhile trade off.

Monocore or Baffles?

A one piece core will be more solid and easier to remove for cleaning and maintenance. However, in general, cone/K baffles are better at overall sound suppression and reducing first round pop.

Full-Size or Kurz?

Pistols are meant to be small, light and concealable. For that reason, with all the recent advances in designs and materials, my preference is for shorter cans. Length and volume, while still important, can be mitigated with good engineering.

Back to the Innovative Arms 9SX – It is an aluminum suppressor with K style baffles (cones) and a small-medium length in comparison to other options on the market.

The 9SX provides the 9mm performance you’ve been looking for in a compact sub-size. Accommodating both pistol and carbine, the 9SX is rated for full auto 9mm fire and disassembles for cleaning. The 9SX includes a booster piston, fixed barrel spacer and a tool for disassembly.

A fixed barrel spacer is for use on firearms with fixed, non-moving barrels. Pistons are available in 1/2 x 28, M13.5x1LH, 1/2 x 36.

  • MSRP: $599
  • Caliber: 9mm
  • Weight: 8.7oz
  • Length: 6.6”
  • O.D: 1.375″
  • Material: Aluminum / Stainless Steel
  • Finish: Type 3 Hard Coat Anodized/ Laser Engraved
  • TPI: 1/2 x 28
  • DB Reduction: 34-35 Dry
  • As with all our silencers, the 9SX can be fired “wet” or “dry”.

The Neilsen device (piston) design is fairly unique with four forward facing teeth.

A fixed barreled spacer is available for pistol caliber carbine use. The spacer fits between the piston and the spring to keep the device from functioning under recoil.

I have to say, the Innovative Arms 9SX has minimal first round pop and is very quiet for its size. Using the 185gr Seismic ammo subsonic 9mm in the GLOCK 48, the 9SX has a pleasant, deep, thumping sound that got me to grin. It’s also avnice size and weight for the G48. This is a fun suppressor.

    I ordered an R9 months ago. When a lot of time elapsed I called YHM to ask about the wait. The guy I spoke to said they were back ordered for more than 6 months. I get a little tired of featured products that are unavailable being promoted.

      @iksnilol I’ve wondered that. I’ve also wondered about doing it with other calibers, such as sizing 55- 62gr .224 bullets for 5.45x39mm.
