Why flutes versus a smooth barrel or another machining? Most external barrel machining offers fairly modest benefits, but in our opinion, flutes do the most. First, when the gun is truly filthy or full of mud, fluted barrels give debris a place to go when your slide is cycling, enhancing reliability. They also tend to “hold” lubricant, keeping your slide lubricated a little longer and distributing it evenly. There are some other lesser impacts, including better barrel rigidity, better cooling, and weight reduction. You can also choose whether you want your pistol to be suppressor ready, by selecting unthreaded like our Shadow Systems Match Barrel to fit G17 or our threaded barrel options. Our custom barrels to fit Glock pistols are finished in three high-performance coatings: Gold Titanium Nitride (TiN), Bronze Titanium CarboNitride (TiCN), and Black Diamond-Like Carbon (DLC). Each of these finishes has been selected by Shadow Systems for their durability and lubricity.
