Zaffiri Precision Bbl P320c Black - Precision Machined Barrel for Sig Sauer P320 Compact

A Zaffiri Precision barrel for the Sig Sauer P320 Compact is a straightforward upgrade for shooters looking to improve accuracy without complicated gunsmithing. This precision-machined replacement barrel drops into your compact slide and handles everything from range sessions to carry use. Built from 416R stainless steel and stress-relieved to exacting specs, it's designed to deliver the kind of performance you'd expect from a match-grade component—tighter tolerances, better lock-up, and consistent shot placement.

The barrel measures 3.9 inches, matching the P320 Compact's profile. Conventional rifling with a 1:10 twist handles standard 9mm ammo reliably, whether you're running lead, plated, or jacketed rounds. The polished chamber and bore reduce friction and feeding resistance. You get a target crown for accuracy and an oversized lock-up area that seats solidly in the slide, minimizing movement under recoil. Heat-treated to a hardness of RC 40–42, it's tough enough for the rigors of regular shooting.

This is a drop-in fit—no fitting, reaming, or special tools required. Pull your original barrel, drop this one in, and you're ready to shoot. It comes ready to go, so there's no break-in or prep work. If you're running a P320 X-Carry, note this barrel is sized for the Compact slide only. USA-made and built to the precision standards serious shooters demand, it's the kind of upgrade that pays for itself in tighter groups and increased confidence downrange.
