The Wilson Combat Glock 17 match barrel is a drop-in 9mm replacement for Gen 3 and Gen 4 Glock 17 pistols, fully machined from 416R stainless steel and heat treated to Rockwell C 40 for a long service life. Wilson Combat holds its tolerances to less than five ten-thousandths of an inch and rates the barrel for groups of two inches or less at 25 yards with quality ammunition. The 1:16 twist conventional broach rifling is the reason many shooters buy it: unlike the factory polygonal bore, it safely shoots lead, jacketed or plated bullets, which opens the door to inexpensive cast reloads. The chamber is glass smooth and concentric with the bore, with the external chamber corners chamfered to reduce friction in feeding. It is a drop-in design, though Wilson Combat notes minor fitting is occasionally needed, so a competition or high-volume Glock 17 gets match accuracy and bullet flexibility in one part.
