The HUXWRX Flow 45 M .45 ACP suppressor in black is a modular titanium can that runs at full length for maximum suppression or drops to a compact K configuration (HUXWRX part no. 3796). HUXWRX Safety Company 3D-prints the whole suppressor from Grade 23 titanium and coats it in C-series high-temperature Cerakote. Full length it measures 8.5 inches and weighs 7.4 ounces, and without the module it measures 6.3 inches at 5.4 ounces. It is built for a .45 ACP pistol or carbine owner who wants one can for both maximum quiet and light carry.
