Wilson Combat Match-Grade Barrel Features The Wilson Combat Match-Grade Barrel is precision machined from 416 stainless steel and hardened to Rc 38-40 giving it the strength and wear resistance needed for a barrel that sees regular use. It is intentionally slightly oversized in the lockup area which tightens the slide-to-barrel fit compared to a factory Glock barrel and reduces play that can affect accuracy. Conventional rifling is used rather than a polygonal profile giving the barrel reliable compatibility with both plated or jacketed bullets and traditional lead ammunition. This flexibility makes it a practical upgrade for shooters who load a variety of bullet types. Measuring 4.5 inches this non-threaded barrel is designed specifically for Glock 17 Gen 3 and Gen 4 pistols and may require minor fitting during installation to achieve the tightened lockup. Its silver stainless finish gives the pistol a distinct two-tone look when paired with a factory black slide. At just over a quarter pound it is a straightforward drop-in style upgrade that does not add significant weight to the pistol. For Glock 17 owners looking to improve accuracy and slide-to-barrel fit the Wilson Combat Match-Grade Barrel offers a proven precision upgrade.
