    SILENCER SATURDAY #181: SIG Sauer MODX-9 - Modular Muffler Magic

    Hello everyone and welcome back to TFB’s Silencer Saturday brought to you by Yankee Hill Machine, manufacturers of the YHM R9 multi-caliber suppressor. Last week we held our breath and suppressed some full-power 10mm rounds. This week we take away one millimeter to honor the silencer gods and check out the SIG Sauer MODX-9 modular, titanium, 3D printed, 9mm suppressor. Finally, after drooling over the SIG MODX line-up at SHOT 2019, I finally get some trigger time of my own. Was it worth the wait? Let’s find out.

    Additive manufacturing, the correct term for 3D printing, will no doubt play a big role in firearms design and production in the future. The reason it doesn’t have a huge foothold at the moment is cost and time – between the metal being sintered, the machinery, and the power requirements, these processes are complex. But the end result are designs that can’t be created with traditional machining. Not only that, but the resulting parts are very strong and durable (some NASA rocket motors are made using additive manufacturing by way of laser sintering). Surely those need to be able to withstand a little heat and pressure.

    But the real question is if these processes are worth the investment to manufacture firearm suppressors when multi-axis milling machines are capable of cranking out parts far faster. The answer, of course, is it depends.

    When I first started writing about additive manufacturing processes being used to make suppressors, the comments were laced with pitchforks and torches level of disbelief. Most people simply couldn’t believe that melted powdered titanium or inconnel would be as strong as their machined counterparts. The fact is, the are usually stronger than turned parts. Then comes the internal designs – 3D printed parts can have geometries that are almost impossible to create with a spinning tool. Engineers are not limited by previous cutting tolerances.

    While the SIG MODX-9 doesn’t appear to have any internal designs that are only capable with additive manufacturing processes, the external surfaces that are used for take-down tool friction points may be difficult with traditional methods like milling. The thin walls between the points look as if they would bend or  break if they had been milled.

    Let’s take a look at the details.

    The newest pistol suppressor line from SIG SAUER features completely modular and configurable titanium baffles for the ultimate, light-weight performance that allows the user to personalize their suppressor for overall length, weight, and sound. The MODX-9 provides class-leading sound performance and can be easily disassembled and reconfigured with fewer baffles when your priority is size over sound. The MODX suppressors feature 21 points of impact adjustment and come with a fixed barrel spacer for carbine use. Each MODX suppressor includes the most popular metric and metric piston for its given caliber.

    The MODX-9 has seven baffle sections, one of which is the dedicated end cap or cone. There is an eighth section called the encapsulator which holds the piston and spring between the piston housing.

    As noted above, the last baffle section has a permanently attached end cap, so when changing lengths, the #7 baffle section is always at the end.

    The disassembly tools are metal wrenches that are easy to use. Just find the correct friction surfaces for each one and squeeze in the right direction.

    The first six baffles are “clipped” or have what are sometimes referred to as “mouse holes”. These relief cuts redirect gasses and bleed off pressure to make suppression more efficient. The #7 end baffle has a cone without a cut, trapping more gas inside the suppressor.

    In its longest configuration and using subsonic ammunition, the MODX-9 is superbly quiet, providing a comfortable shooting experience. And it’s light. Very light. It feels like 75% of all of the MODX-9’s weight is in the piston assembly.

    Removing one baffle section was slightly noticeable, but successive shortening made things louder quickly. Somewhere between baffles four and five the “hearing safe” designation drops off. I still recommend shooting all centerfire rounds with hearing protection. The sweet spot between length and suppression is four baffles. This setup is quiet enough to still be fun, but short and light enough to be portable and concealable.

    I do wish that SIG had designed this suppressor with nine baffles instead of seven. I think there is still some room for additional reductions at the expense of adding about two inches. The coating/surface treatment scratched a bit easier than I would have liked, but it’s not a dealbreaker.

    Overall, this is a fun suppressor that is very quiet, modular, light and is made with next-generation manufacturing processes. It includes two pistons and a fixed barrel spacer when other manufacturers aren’t including any pistons at all.

    The SIG Sauer MODX-9 gets two thumbs up from me.

    Thanks for reading. Be safe and we’ll see you here next weekend for another Silencer Saturday.

    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.

    In this episode of TFBTV, James Reeves interviews Jason St. John of Sig Defense about Sig’s new 3D printed titanium and inconel steel. Sig is going additive manufactured aka 3D-printed *only* in the future and moving forward, their rifle and pistol silencers will be 3D printed titanium or inconel. James discusses the new line including the Sig SLH and SLX, a subsonic and supersonic-optimized pair of rifle silencers (respectively) in 5.56 or .30cal, and the modular Sig MOD-X, a removable-baffle design pistol can coming in 9mm or .45 flavors.
