FAQ
Is this a drop-in barrel, or will it require fitting?
This SIG Sauer barrel is manufactured to be a direct drop-in replacement for factory-spec slides. It should install without fitting, but as with any aftermarket part, a function check is always recommended.
Will the Plum finish wear off quickly?
No. The Plum color is a Physical Vapor Deposition (PVD) coating, which is significantly harder and more wear-resistant than traditional finishes like Cerakote. It is bonded to the steel and will maintain its appearance through extensive use.
