Are aftermarket Glock barrels more accurate?

For Glocks, the stock barrel is usually very accurate. The main reasons you would want to upgrade to an aftermarket barrel are because you want to add a threaded barrel for the attachment of a muzzle device like a compensator, your current barrel is worn down or in bad shape, or because you simply want to add more personal flair to your weapon.

Does Glock sell barrels?

Yes, you can buy an OEM Glock barrel from us right here if you want to replace your current barrel with an original Glock barrel instead of an aftermarket version.
