The HUXWRX Flow 9 M suppressor is a modular 9mm pistol can machined from grade 23 titanium and finished in matte black C-Series Cerakote (HUXWRX part no. 3870). It uses the company’s flow-through design, which sends gas forward out of the can instead of dumping it back into the action and toward the shooter’s face. The modular layout lets you run it at full length for the quietest setup or drop to the shorter K configuration when a compact, lighter host matters more. A 1/2×28 booster assembly ships with it for reciprocating-barrel pistols, and the same can is rated for several rimfire and subsonic rifle cartridges. It is a strong fit for a shooter who wants one light titanium can to cover a carry pistol, a 9mm PCC and a .22 trainer.

Key Specifications

• The primary caliber is 9mm, the cartridge the Flow 9 M is sized around for pistol and pistol-caliber carbine hosts.
• HUXWRX also rates it for .22 LR, .17 HMR, 5.7x28mm, .300 Blackout subsonic and .350 Legend, so one can covers several hosts.
• Construction is grade 23 titanium, an aerospace alloy that keeps weight down without giving up durability.
• Full configuration length is 8.6 inches, the setup to choose when sound reduction comes first.
• K configuration length is 6.3 inches, trimming the can for a shorter, handier pistol package.
• Diameter is 1.38 inches, slim enough to sit comfortably on a handgun.
• Full configuration weight is 8.5 ounces, light for a can that handles centerfire pistol pressures.
• K configuration weight is 6.3 ounces, which keeps the muzzle from feeling front heavy on a compact pistol.
• It ships with a 1/2×28 booster assembly, the mount a tilting-barrel pistol needs to cycle reliably with a can attached.
• HUXWRX offers 3-lug, stiction and direct-thread adapters for hosts that do not need the booster.
