Your GLOCK pistol, as it comes from the factory, is as accurate as it will ever be as long as it retains the stock barrel. Customizing your pistol via grip work, better trigger, upgraded sights, or even a optic, does not make it any more accurate than it currently is…it just makes it easier for you to extract the accuracy that’s already there. The only way to make your pistol more accurate is to add a quality match/precision barrel. There are many aftermarket barrels for GLOCK pistols on the market, ranging significantly in quality and price, with a wide variety of features, some of which are purely cosmetic and some which are functional, threaded for suppressor use, drop-in or fitted.
While some fitted match/precision barrels do provide a slight increase in accuracy over a comparable quality drop-in barrel, we feel that the extra hair of accuracy you get from a fitted precision barrel in a pistol isn’t worth the cost in reliability for a duty/carry sidearm. So in our opinion, fitted precision barrels are best for competition/shooting sports use. This is why our ADVANTAGE match barrels are designed to be 100% drop in. NOTE: due to the significantly tighter tolerance of our barrels vs stock, and the tolerance variations found in GLOCK pistols, sometimes one of our barrels might need to be fitted to your pistol. In those cases, we will fit the barrel for you at no charge.
Boresight Solutions ADVANTAGE match barrels are some of the most accurate and precise drop-in pistol barrels available, and are proudly made in Florida, USA. Our barrels are made from 416R Chromium Stainless Steel, which is ideal for firearm barrel use and specifically +P rated chamber support due to its high tensile strength and corrosion resistance, and rifled 1-1o” to effectively accommodate popular and common practice and carry 9mm bullet weights/profiles. They are also double-honed (rough and finish) to achieve a minimum smooth surface finish of 16RA. These high performance barrels are cut to extremely tight tolerances inside and out, with a final dimensional standard of +/- 0.003″. Each Boresight Solutions ADVANTAGE barrel is cut, rifled, and individually inspected for groove dimensions and broach finish.
So if you’re looking for an immediate, measurable, and reliable improvement in accuracy for your carry sidearm… and is backed by a company that’s been building hard-use custom Duty/Carry pistols since 2002…then a Boresight Solutions ADVANTAGE match barrel is what you want in your GLOCK.
