P80 Thr/Flu Brl N/Sght 15rd

Overview

The P80 Thr/Flu Brl N/Sght 15rd is a factory-spec component from Polymer80, designed for builders who demand precision without unnecessary complexity. This threaded and fluted barrel assembly includes a non-serrated sight and is configured for 15-round magazines. As a direct-from-manufacturer part, it ensures proper headspace and timing for reliable function in compatible frames. This p80 thr/flu brl n/sght 15rd unit is machined from 416R stainless steel with a black nitride finish, offering corrosion resistance and consistent bore dimensions. It is intended for use with standard 9mm Luger ammunition and fits Polymer80 compact and full-size frames requiring a 15-round magazine interface.

Features & Specs

This p80 thr/flu brl n/sght 15rd barrel is manufactured to Polymer80’s exacting tolerances, which means you get drop-in fitment with minimal break-in. The threaded muzzle (1/2×28 TPI) accommodates standard compensators or suppressors, while the fluting reduces overall weight without compromising barrel rigidity. The non-serrated front sight is pre-installed and correctly aligned for a standard-height rear sight.

• Threaded muzzle: 1/2×28 TPI with protective thread cap included
• Fluted profile: reduces barrel weight by approximately 15% versus non-fluted equivalent
• 416R stainless steel with black nitride finish: rated for extended service life

Technical specifications include a 1:10 twist rate, 4.5-inch overall length, and a 0.355-inch bore diameter. The barrel is headspaced for factory 9mm ammunition and features a fully supported feed ramp. The p80 thr/flu brl n/sght 15rd is compatible with all Gen3-style slide assemblies that accept standard 9mm barrels.

Who It Is For

This product is for builders assembling a Polymer80-based pistol with a 15-round magazine capacity. It suits shooters who want a threaded barrel for suppressor use or muzzle devices, but prefer the weight savings of a fluted profile. The non-serrated sight is ideal for those who will replace it with aftermarket suppressor-height sights or who prefer a clean sight picture. The p80 thr/flu brl n/sght 15rd is also appropriate for gunsmiths completing customer builds who need a reliable, spec-compliant barrel that does not require custom fitting. It is not intended for competition shooters requiring ultra-light bull barrels or for those using extended-length magazines requiring different chamber geometries.

• Builders completing a Polymer80 compact or full-size frame with 15-round magazine compatibility
• Shooters who require a threaded barrel for suppressor use or compensator attachment
• Users seeking a fluted barrel to reduce overall weight without sacrificing accuracy
