Unmatched Build Quality

Premium-Grade Materials

The Backup Tactical 9mm barrel for the SIG P320 Compact is crafted from 416R stainless steel, a material chosen for its superior strength, corrosion resistance, and ability to maintain tight tolerances. This grade of stainless steel is commonly used in high-end precision rifle barrels and guarantees long-lasting durability and thermal stability under repeated fire.

Whether you’re shooting thousands of rounds at the range, training in adverse weather conditions, or depending on your weapon in a defensive scenario, this barrel is built to withstand the rigors of everyday carry and tactical use.

Threaded for Suppressor Use

The 1/2×28 thread pitch is the industry standard for 9mm suppressors and compensators. This allows seamless integration with a wide range of muzzle devices, including suppressors, muzzle brakes, and thread protectors. Each barrel comes with a thread protector to maintain the integrity of the threading when no device is attached.

This threaded feature is not just tactical—it’s practical. Suppressors reduce felt recoil, muzzle rise, and sound signature, making it easier to stay on target and shoot more comfortably for longer sessions.

---

Cerakote Flat Dark Earth Finish

The barrel is finished in Flat Dark Earth Cerakote, a rugged ceramic-based coating renowned for its toughness, corrosion resistance, and heat tolerance. The FDE color not only adds a tactical and aesthetic flair but also reduces glare and blends seamlessly with custom builds or factory FDE P320 frames and slides.

This coating ensures your barrel remains protected against wear, solvents, moisture, and harsh field conditions. It’s an investment in performance and visual appeal.

---

Drop-In Compatibility

The Backup Tactical Barrel is a true drop-in upgrade for the SIG P320 Compact. No gunsmithing, fitting, or modification is needed. Simply remove your existing factory barrel and install the Backup Tactical version in minutes.

Thanks to tight machining tolerances and perfect fitment, you’ll enjoy a noticeable boost in accuracy, consistency, and reliability. The barrel locks up precisely with the slide, resulting in a solid shooting platform that performs shot after shot.

---

Enhanced Accuracy and Consistency

Precision shooters demand more than just reliability—they demand accuracy. This barrel is designed to improve your SIG P320 Compact’s inherent accuracy by optimizing chamber dimensions, rifling geometry, and lockup consistency.

Whether you’re shooting with factory ammo or custom reloads, suppressed or unsuppressed, this barrel delivers tight groupings and predictable performance. The match-grade rifling ensures that each projectile is stabilized for consistent flight, improving target engagement from close-quarters to mid-range distances.
