The Shadow Systems Match Barrel (brand part number SG9CL-00-03TSPL-NIT) is a threaded, spiral-fluted upgrade built for the MR918 and DR pistol models in 9mm. Shadow Systems machines it from 416R stainless steel with a 1-in-10-inch broach-cut rifling twist, and the spiral fluting cuts reciprocating mass while giving dirt and fouling somewhere to exit as the slide cycles. It is precision-machined for a tighter drop-in fit at the critical lock-up points than a factory barrel, which is the biggest driver of its accuracy gain, and the threaded muzzle accepts a compensator, suppressor, or other muzzle device. Every Shadow Systems barrel is made in the U.S.A. from U.S.-sourced materials.
