Product Description The Shadow Systems Match Grade 4.5" Threaded Spiral Fluted Barrel is a precision-crafted upgrade designed specifically for Shadow Systems MR920, XR920, and MR918 pistols. Engineered to deliver more consistent lockup without compromising reliability, this barrel features a fully supported chamber rated for hot +P ammunition and lead bullets. Each barrel undergoes rigorous proof testing, surviving 5 proof rounds, ensuring confident performance with any mainstream commercially available 9MM ammunition. The black nitride (Titanium Copper Nitride) finish provides exceptional corrosion and wear resistance, while the spiral fluted body reduces weight and improves heat dissipation. The threaded muzzle at 1/2x28 makes this barrel suppressor-ready straight out of the box.
