Good morning everyone and welcome back to another edition of TFB’s Silencer Saturday brought to you by Yankee Hill Machine, manufacturers of the awesome Turbo K 5.56 suppressor. Last week we discussed how everyone needs at least one rimfire suppressor. This week we get an exclusive look at the new SIG Sauer suppressors that will be available starting in August or September. Will you want to add one to your armory? I think so. Follow me for some initial feedback and performance evaluations.

SILENCER SATURDAY #135: SIG Sauer Suppressors – New 3D Printed Hotness

Before you decide to slit my throat for not including some of the most important details and specifications, I don’t have exact weights, measurements and pricing to share yet. Although stout, none of the Inconel models felt unbearably heavy to me.

Here’s what we know (I promise to update you all as we get more information):

SIG Sauer MODX 9 and MODX 45 pistol caliber suppressors:

• Titanium 3D printed modular suppressors
• Piston and direct thread options (no three lug yet)
• Availability: Soon

SIG Sauer SLX Rifle Suppressors:

• Inconel additive manufacturing construction
• Designed for high pressure/velocity rounds
• Forward venting to drastically reduce blowback
• Near zero flash signature
• Direct thread and QD mounting capability on every silencer.
• 5.56mm/7.62mm
• Two or three lengths
• Availability: August/September

SIG Sauer SLH Rifle Suppressors:

• Titanium additive manufacturing construction
• Designed for low pressure/subsonic rounds
• Focus on noise reduction
• Direct thread and QD mounting capability on every silencer.
• Availability: September/October

We shot the SLX suppressors on the NGSW Submission SIG Light Machinegun and MCX SPEAR select fire rifle in 6.8x51mm (.277 Fury), 5.56mm MCX Virtus and on a .308 piston rifle. With the extremely low back pressure design, there was no need to adjust the gas settings on any of the platforms.

Evaluating silencers used with supersonic ammunition is difficult without a decibel meter specifically designed to evaluate gunshots. But they each performed very well on their respective platforms. I stood 10 feet away and parallel to the muzzle of the LMG and was surprised at the lack of blast and noise from a midsize suppressor. Very scientific, I know.

Here’s a quick montage video from our own “pees sitting down but is still the best damn producer in the business” Ryan Ogborn, showing the forward venting and robustness of the SIG Sauer SLX 3D printed suppressors.

Below, from top to bottom:

• 7.62mm
• 5.56mm (Silver, finish removed)
• 6.8mm NGSW project
• 300BLK
• MODX9

As a reminder, these are pre-production prototypes. Colors and markings may be different when they are available for purchase.

TFBTV got a crack at the MODX45 modular pistol suppressor after SHOT Show 2020 thanks to our friends at Silencer Shop.

Today on TFBTV, Ryan looks at Sig Sauer’s 3D Printed Titanium Silencer, the MODX45. How does it perform on the Sig Sauer P220? Check today’s video to see (hear?) for yourself. NOTE: This silencer is NOT on the market yet and likely won’t be for about a year after this video publishes. Read more at: https://www.thefirearmblog.com/blog/2020/03/05/sig-sauer-modx45/

Notice how the 6.8mm can has a slightly larger diameter.

James will have a more detailed interview on TFBTV about the new suppressors with the SIG Sauer team shortly.

The QD mounting solution for the SLX and SLH models are different from the SRD556 and SRD762 QD models. While this may be disappointing to previous generation owners, I had a chance to speak with SIG silencer guru John Hollister this week.  The new system is a simpler design and is easier to manipulate, but the older QD mounts will still be manufactured for many years to come.

Speaking with Robbie Johnson, head of SIG Sauer’s suppressor product development team, the new QD system revolves around a taper mating surface, internal cams followed by threads. The 6.8mm machinegun suppressor was mounted for thousands and thousands of rounds of fully automatic fire before removal and it unscrewed without any issues.

Different from the last generation, owners will be able to buy one suppressor model and use either a direct thread mounting unit or a QD mounting unit. Previously with the SRD cans it was a choice of one or the other.

The system operates with a simple 10 degree twist between either a lock or unlock symbol.

Obviously, the unlock position allows the mount to be unscrewed from the flash hider whereas the lock position keeps everything together.

If you wrench down on your silencer when mounting or need to remove it from the mount when it’s still hot, a tool is provided that mates up with four notches on the muzzle field extra leverage.

Below you can just make out the the internal cams that engage the mount in the locked position.

We’ll have a more detailed review of the SLX when I get my hands on some of the first production cans in a few weeks. Until then be safe, have fun and we’ll see you here next weekend for another edition of Silencer Saturday.
