FAQ

Is this a drop-in barrel, or will it require gunsmith fitting?
This barrel is manufactured to SIG SAUER specifications for a drop-in fit in the P320C. It should install directly into your slide without modification, though we always recommend checking function and headspace after installing any critical component.

Will this threaded barrel work with my P320C’s existing holsters?
Likely not. The added length and diameter of the threaded portion will prevent the pistol from seating in holsters designed for the non-threaded, flush-fit factory barrel. You will need a holster specifically designed for a P320C with a threaded barrel.
