Swap out your factory Sig P320 X-Five barrel for the Rival Arms RA20P501E Precision 9mm Drop-In Barrel and unlock tighter groups without a gunsmith visit. This 5-inch match-grade barrel is built from 4340H steel and finished in distinctive gold PVD coating—a hard-wearing surface that resists corrosion and wear while giving your pistol a competition-ready look. Drop-in design means you're back on the range in minutes, making this the practical upgrade for shooters chasing accuracy at the range or in IPSC/USPSA competition.
The heart of precision is a well-made bore. Rival Arms machines each barrel from a billet and hand-inspects the finished product. The 1:10 twist rate and 6-groove rifling profile are optimized for 9mm, and the target-crowned muzzle ensures consistent bullet release shot to shot. The PVD coating isn't just cosmetic—it creates a durable barrier against the solvents, oils, and wear that softer finishes can't handle, keeping your barrel running smooth through thousands of rounds.
Whether you're a competition shooter looking to dial in your X-Five or a serious handgun enthusiast who refuses to settle for factory accuracy, this barrel pairs precision manufacturing with no-fuss installation. No special tools, no guesswork, no trip to a gunsmith.
