1. Engineered for the Elite: Why This Barrel Stands Out

Backup Tactical is renowned in the firearms industry for crafting exceptionally reliable, match-grade barrels that go beyond basic performance. This 9MM threaded barrel for the SIG P320 Compact reflects years of engineering, metallurgy, and testing, culminating in a product that delivers:

• Improved accuracy

• Enhanced suppressor compatibility

• Durability under high round counts

• Drop-in installation

• Tactical aesthetics

Designed to elevate your P320 to a whole new level, this barrel merges form and function in one impressive upgrade.

2. Compatibility with SIG P320 Compact

This barrel is a perfect match for the SIG SAUER P320 Compact platform. If you own a factory-configured P320 Compact 9mm pistol, you’ll be pleased to know this barrel installs seamlessly without the need for fitting or modification.

• Fits: SIG SAUER P320 Compact (9MM only)

• Does not fit: Full-size or subcompact frames

The barrel’s external dimensions align precisely with factory specs, ensuring smooth operation with factory slides, OEM or upgraded recoil springs, and most aftermarket holsters.

---

3. Threaded Design for Suppressor and Comp Use

A standout feature is the threaded muzzle, allowing for the attachment of suppressors, compensators, or thread protectors.

• Thread pitch: 1/2×28 TPI (standard for 9mm accessories)

• Thread protector included: Yes

• Suppressed-ready: 100% compatible with most 9MM suppressors on the market

This makes the Backup Tactical barrel ideal for users seeking suppressed shooting with their P320 Compact. Whether for home defense, range training, or tactical missions, adding a suppressor is easier than ever.

4. Precision-Crafted for Accuracy

At the heart of every great barrel lies exceptional rifling, tight tolerances, and superior craftsmanship. Backup Tactical ensures each barrel undergoes rigorous inspection, CNC machining, and hand finishing to maintain match-grade precision.

• Material: 416R stainless steel

• Finish: Black nitride (QPQ treated)

• Rifling: Conventional (non-polygonal) for broader ammo compatibility

• Twist Rate: 1:10 RH

With this barrel, shooters can expect tighter groups, less deviation, and more confidence at distance — especially when paired with high-quality 9MM ammunition.

---

5. Durable Black Nitride Finish

Durability meets sleek aesthetics in the barrel’s black nitride finish. This isn’t just a cosmetic choice — it’s a premium surface treatment that improves barrel lifespan, corrosion resistance, and overall performance.

Benefits of Black Nitride Coating:

• Resists moisture, sweat, and carbon buildup

• Reduces friction and heat wear during rapid fire

• Maintains color and finish over time

• Less prone to galling with steel components

Unlike traditional bluing or parkerizing, nitride-treated barrels withstand the punishment of thousands of rounds without degrading in performance or appearance.

---

6. Easy Drop-In Installation – No Gunsmith Required

One of the biggest advantages of the Backup Tactical barrel is its drop-in design. No need to send your firearm to a gunsmith or machine shop — simply field strip your P320, swap the barrels, and reassemble.

• Tool-free installation

• No slide mods necessary

• Compatible with factory recoil assemblies

Within minutes, your pistol is upgraded and suppressor-ready.

---

7. Designed for Suppressor Use: Gas Optimization and Sound Reduction

Suppressor enthusiasts know that not all barrels are created equal. The Backup Tactical SIG P320 Compact barrel is engineered to deliver optimal cycling when used with a suppressor. Its threading is precisely aligned, ensuring a straight bore axis for proper suppressor attachment, minimizing baffle strikes or alignment issues.

Additionally, the barrel’s rifling and gas dynamics help maintain consistent backpressure, ensuring your slide cycles reliably even with subsonic loads.

---

8. Tactical Aesthetics That Demand Attention

This barrel doesn’t just perform — it looks aggressive and professional. The black nitride coating, fluted exterior, and laser-engraved branding give your firearm a custom, high-end look.

Whether you’re:

• Building a duty-ready suppressed pistol

• Customizing your EDC gun

• Creating a showpiece for your collection

…this barrel delivers the visual upgrade your SIG P320 deserves.

---

9. Tested and Trusted by Professionals

Backup Tactical barrels are field-tested by law enforcement, military, and tactical professionals. They’re designed not just for the range, but for real-world use — where reliability, precision, and rugged construction can mean the difference between mission success and failure.

Thousands of shooters trust Backup Tactical barrels in:
