Real-World Testing: Putting SIG SAUER P320 Full Size Threaded Pistol Barrel, 9mm Luger to the Test

First Use Experience

I took my SIG SAUER P320 equipped with the new SIG SAUER threaded barrel to my local outdoor shooting range. I wanted to see how it performed with and without a suppressor. The range provided a controlled environment to test accuracy and reliability.

The barrel performed exceptionally well under various conditions. I tested it in dry conditions and with the barrel moderately heated after several magazine dumps. There were no malfunctions.

The installation was straightforward, and the barrel seated perfectly in my P320 slide with no modifications needed. The only adjustment needed was confirming the zero on my red dot optic due to the change in barrel.

I experienced no issues or surprises during my first range session. The threads were clean and easily accepted my suppressor. The overall feel was consistent with the original barrel, just with added length and threading.

Extended Use & Reliability

After several months of regular use, the SIG SAUER P320 Full Size Threaded Pistol Barrel, 9mm Luger continues to perform flawlessly. I have put hundreds of rounds through it with various types of 9mm ammunition, including standard FMJ, hollow points, and +P rounds.

The Nitron finish has proven to be very durable, showing minimal signs of wear and tear despite frequent use and cleaning. I’ve noticed only slight wear marks at the contact points within the slide, which is expected.

Maintaining the barrel is straightforward; regular cleaning with standard gun cleaning solvents and lubricants keeps it in optimal condition. I typically clean the barrel after each range session to prevent any buildup of carbon or fouling.

Compared to aftermarket barrels I’ve used in other pistols, the SIG SAUER barrel stands out in terms of reliability and consistent performance. It provides the expected accuracy and reliability from an OEM part.

Breaking Down the Features of SIG SAUER P320 Full Size Threaded Pistol Barrel, 9mm Luger

Specifications

• Caliber: 9mm Luger. This is a standard and widely available caliber, making it easy to find ammunition.
• Barrel Length: 5.5 inches. The increased length compared to the stock barrel provides enhanced accuracy and muzzle velocity.
• Threads per Inch: 1/2×28. This is a very common thread pitch for 9mm suppressors and muzzle devices, ensuring wide compatibility.
• Finish: Nitron. The Nitron finish provides excellent corrosion resistance and durability, protecting the barrel from wear and tear.
• Material: Heat-treated steel. The heat-treated steel construction ensures toughness and longevity, withstanding high round counts and demanding conditions.
• Compatibility: SIG SAUER P320 Full Size (with loaded chamber indicator), EXCEPT P320 X-FIVE slide. It’s critical to note the incompatibility with the X-FIVE slide to avoid fitment issues.

These specifications matter because they directly influence the barrel’s performance, durability, and compatibility with other accessories. The 1/2×28 threading allows for easy attachment of suppressors and compensators, while the 5.5-inch barrel length improves accuracy. The Nitron finish and heat-treated steel construction ensure the barrel can withstand the rigors of frequent use.

Performance & Functionality

The SIG SAUER P320 Full Size Threaded Pistol Barrel, 9mm Luger excels in its primary function: providing a reliable and accurate platform for suppressor or compensator use. Accuracy is noticeably improved compared to the stock barrel, particularly at longer ranges.

Its strengths lie in its consistent performance, reliable threading, and durable construction. The only area for potential improvement is the lack of a thread protector included with the barrel.

It meets my expectations as a high-quality OEM barrel, offering enhanced versatility and performance without sacrificing reliability.

Design & Ergonomics

The build quality is excellent, with precise machining and a flawless Nitron finish. The barrel is noticeably heavier than some aftermarket options, but this contributes to its stability and accuracy.

The barrel is user-friendly, requiring no special tools or modifications for installation in a compatible SIG SAUER P320 slide. There is virtually no learning curve.

Durability & Maintenance

The heat-treated steel construction and Nitron finish suggest that this barrel will last for thousands of rounds with proper care. I expect it to outlast many aftermarket options.

Maintenance is simple, requiring only regular cleaning and lubrication to prevent corrosion and fouling. The Nitron finish makes cleaning easier compared to barrels with less durable coatings.

Accessories and Customization Options

The primary customization option is the ability to attach suppressors, compensators, or other muzzle devices using the 1/2×28 threads. Many brands, such as SilencerCo, Dead Air, and SureFire, offer compatible accessories.

While the barrel itself doesn’t come with any accessories, it is designed to work seamlessly with existing SIG SAUER P320 components, such as slides, recoil springs, and guide rods. The 1/2×28 threading is an industry standard, ensuring a wide range of compatible accessories.
