SIG SAUER P320 Carry X-Series Caliber X-Change Kit Review

First Impressions of SIG SAUER P320 Carry X-Series Caliber X-Change Kit

The SIG SAUER P320 Carry X-Series Caliber X-Change Kit promises modularity and adaptability, concepts that deeply resonate with me after a decade spent advising on tactical and outdoor gear. SIG SAUER has built a solid reputation, and this kit aims to extend the P320’s already impressive versatility. My initial hope is that it delivers a truly seamless and reliable caliber conversion, enhancing the P320 platform without compromising its core strengths.

I’ve always appreciated the P320’s adaptability, but I needed a way to easily switch between calibers for different scenarios – from range practice with 9mm to having the option for .40 S&W or .357 SIG for self-defense while backpacking in bear country. The promise of a straightforward caliber change without needing a completely separate firearm was incredibly appealing.

Unboxing the SIG SAUER P320 Carry X-Series Caliber X-Change Kit, I was immediately struck by the quality of the components. The slide finish is excellent, the barrel looks precisely machined, and the included magazine feels robust. The weight is comparable to my existing P320 Carry slide, suggesting a well-balanced system.

Compared to purchasing a completely separate P320 in a different caliber, this kit offers a significant cost saving and reduces the number of firearms I need to manage. I also considered aftermarket conversion barrels, but the SIG SAUER kit ensures factory-level quality and reliability. Ultimately, the integrated X-Series features and the SIG SAUER name led me to choose this kit.

My first impression is one of cautious optimism. The components look and feel high-quality, but the real test will be how it performs on the range. I’m excited to see if this kit lives up to its promise of easy caliber conversion and consistent performance.

Real-World Testing: Putting SIG SAUER P320 Carry X-Series Caliber X-Change Kit to the Test

First Use Experience

My initial testing took place at my local shooting range, focusing on both 9mm and .40 S&W configurations. I wanted to assess the ease of the caliber exchange and the accuracy of each setup. The weather was clear and dry, providing optimal shooting conditions.

The caliber exchange process was surprisingly straightforward; after field stripping the pistol, swapping the slide assembly, barrel, and magazine took less than a minute. The 9mm configuration performed flawlessly, with consistent accuracy at 15 yards. The .40 S&W, however, had a slightly different feel with noticeably more recoil, but was still manageable and accurate after adjusting my grip.

After the first few magazines of .40 S&W, I experienced a couple of failures to extract, which concerned me. I disassembled and thoroughly cleaned the .40 S&W barrel and chamber before resuming testing. The issue seemed to resolve itself after the cleaning, but it raised a red flag about potential reliability issues with that caliber.

Extended Use & Reliability

After several weeks of consistent use, the SIG SAUER P320 Carry X-Series Caliber X-Change Kit has generally proven reliable, though not without some caveats. The 9mm configuration remains flawless, consistently delivering accurate and reliable performance. The .40 S&W continues to be accurate but requires more frequent cleaning to avoid extraction issues, particularly with certain brands of ammunition.

After approximately 500 rounds, the slide finish shows minimal signs of wear around the ejection port. Routine cleaning and lubrication are essential, but the kit itself is relatively easy to maintain, with no unusual wear patterns observed. The X-Series grip module is easy to keep clean.

Compared to my experience with other conversion kits, the SIG SAUER kit is definitely a step up in terms of build quality and ease of installation. However, the occasional hiccups with the .40 S&W configuration prevent it from being a perfect, universal solution. It outperforms many aftermarket options but requires careful attention to maintenance and ammunition selection.

Performance & Functionality

The SIG SAUER P320 Carry X-Series Caliber X-Change Kit generally performs its job effectively, providing a functional caliber conversion for the P320 Carry. Accuracy with both 9mm and .40 S&W is acceptable, although the .40 S&W requires more attention to cleaning and maintenance. Usability is excellent due to the easy caliber exchange process.

The primary strength is the ease of caliber conversion and the factory-level quality of the components. A potential weakness is the occasional extraction issues with the .40 S&W configuration, which requires more frequent cleaning and careful ammunition selection. The magazine capacity is appropriate for the calibers offered in the kit.

Overall, the kit meets my expectations for a SIG SAUER product. It offers a convenient and relatively reliable way to switch between calibers, though the .40 S&W configuration requires extra vigilance.

The X-Series features, such as the enhanced slide serrations and X-Ray3 sights, improve the overall ergonomics and handling of the pistol.

Durability & Maintenance

The stainless steel construction and Nitron finish suggest that the kit will last a long time with proper care. Regular cleaning and lubrication are essential, especially with the .40 S&W configuration. The parts are relatively easy to replace if necessary, due to the P320’s modular design.

Maintaining the SIG SAUER P320 Carry X-Series Caliber X-Change Kit is relatively simple, requiring only basic cleaning supplies and lubricants. The occasional extraction issues with the .40 S&W can be mitigated by more frequent cleaning of the chamber and barrel.
