FAQ
Is this a drop-in barrel, or will it require fitting?
This Glock barrel is manufactured to strict specifications for a drop-in fit. It should install directly into your OEM slide without modification, though slight fitting is always possible with aftermarket parts.
Does the copper finish wear off easily?
The copper color is a Physical Vapor Deposition (PVD) coating, which is significantly more durable than a simple plating or paint. It is highly resistant to holster wear, corrosion, and chipping under normal use.
