At SHOT Show 2026, the HUXWRX booth wasn’t pushing gimmicks. Instead, they showcased the FLOW 45: a modular .45-caliber handgun suppressor that prioritizes simplicity and weight reduction.
The FLOW 45 is designed for shooters who want fewer parts, fewer tools, and less hassle when running a pistol can.
3D-Printed Titanium, One Solid Unit
The suppressor is fully 3D printed from Grade 23 titanium. Rather than using stacked or removable baffles, each section is a single monolithic piece.
This design choice eliminates common failure points and simplifies maintenance. There’s less concern about components coming loose, and no baffles to misalign when switching between configurations.
Modular Length
In its full configuration, the FLOW 45 measures 8.5 inches. Removing the modular top section shortens it to 6.3 inches. Importantly, this change doesn’t require removing an end cap or reinstalling internal parts. Simply unthread that section, and you are good to go.
The only additional piece is a simple thread protector, and the entire conversion is done by hand. No tools are required, and there are no small parts to keep track of. For shooters who actually switch between configurations, this is a practical setup rather than a theoretical one.
Weight and Pistol Compatibility
Total weight is listed at 7.5 ounces with all components installed. For a .45 suppressor, that’s on the lighter side. The lighter weight also helps reduce the front-heavy feel and can improve handling.
The FLOW 45 ships with a booster, making it ready for handgun use out of the box. There’s no need to source additional mounting hardware before putting it on a pistol.

Sound Performance and Real-World Expectations
At the time of SHOT Show, sound reduction numbers were still pending. HUXWRX acknowledged that decibel ratings vary widely based on barrel length, ammunition, and host firearm, so they didn’t want to give an estimate.
The longer configuration provides a modest reduction advantage over the short setup, but the difference is not dramatic.
Pricing and Availability
The FLOW 45 carries an MSRP of $850, with many dealers expected to sell under $800. Shipping is scheduled to begin immediately following SHOT Show.
The FLOW 45 doesn’t try to redefine handgun suppression. Instead, it offers a lightweight, modular option with fewer parts and a focus on usability, something many shooters will likely appreciate.
Be sure to keep an eye on the HUXWRX website because the FLOW 45 should be added soon.

Why no Db before and after comparisons or even just the Db?
Also.. why would I be changing configurations?
so how does one 3d print metal? seems to me that it can’t be fused together properly.
Manufacturers measure and advertise, and customers look at a measured Db reading for a suppressor which is a very poor method of evaluation. A manufacturer (or better the entire industry) should select a point X inches and Y degrees on the Z axis from the muzzle of gun and the same for the muzzle of the suppressor and publish the difference. And use this standard across their entire line of products. The barrel length (or firearm model) and ammunition used should be published and identical for all suppressors of a given caliber. Finally, environmental conditions need to be included. I suspect a can chilled down to a sub zero temperature will be quieter than one at 72F and a measurement at 100ft altitude (real or simulated) will be different than one taken at 10,000ft with 2/3 the air pressure. Equipment used, sensor orientation, etc. would be icing on the cake. Then we would have useful data to aid in selecting the best product for our needs.
