Wilson Combat Match Grade Barrel for Glock 17 Gen 1-4 9mm Luger 1 in 16" Twist 4.49" Stainless Steel

Machined from aircraft grade stainless steel forging and heat-treated to R/C 40 for maximum service life. Critical tolerances are held to less than .0005" to provide phenomenal accuracy (test barrels at the Wilson factory routinely shoot groups of 1/2" at 25 yards). Barrels are slightly oversized in the lock-up areas and require fitting by qualified gunsmith. DISCLAIMER: This product is not manufactured, authorized, endorsed, or warranted by GLOCK.
