First Impressions of Faxon Firearms EXOS-515 Pistol Compensator for SIG P320
Pistol compensators have always intrigued me. They promise reduced recoil and faster follow-up shots, making them a tempting upgrade for any serious shooter. That’s why I was eager to get my hands on the Faxon Firearms EXOS-515 Pistol Compensator for SIG P320.
As a seasoned firearms enthusiast with over a decade of experience, I’m always on the lookout for products that genuinely enhance performance, not just add aesthetic flair. I had been experiencing excessive muzzle flip with my SIG P320 during rapid firing drills, a problem I hoped the EXOS-515 could mitigate.
Upon unboxing, the EXOS-515 presents a sleek, black anodized finish. The 6061 aluminum construction felt surprisingly lightweight, raising initial concerns about its ability to effectively manage recoil. Compared to heavier steel compensators I’ve used on other platforms, the Faxon offering seemed almost too minimalist. I chose this compensator primarily due to Faxon Firearms’s reputation for quality barrels; I hoped their expertise would translate to this accessory. My first impression was cautiously optimistic, a mix of intrigue and skepticism that only range time could resolve.
Real-World Testing: Putting Faxon Firearms EXOS-515 Pistol Compensator for SIG P320 to the Test
First Use Experience
I tested the Faxon Firearms EXOS-515 Pistol Compensator for SIG P320 at my local shooting range. The environment was controlled, allowing me to focus solely on the compensator’s performance. Initial installation was straightforward, though I meticulously followed Faxon’s instructions, applying the included thread locker to the set screws.
The first few magazines revealed a subtle but noticeable reduction in muzzle climb. However, the set screws began to loosen after about 50 rounds. I noticed this issue despite following the torquing guidance. I tightened them again, but the problem persisted, requiring constant monitoring and adjustment. This occurred with both 115gr and 124gr ammunition.
Extended Use & Reliability
After several range sessions spanning a couple of months, my concerns regarding the EXOS-515’s reliability grew. The set screws continued to be a major issue, consistently backing out despite repeated applications of thread locker (including higher-strength alternatives). Furthermore, the anodized finish began to show wear around the ports, suggesting a lack of resilience to the high-pressure gases.
Cleaning the compensator was simple, requiring only basic solvents and a brush. However, the constant need to re-tighten the set screws overshadowed any ease of maintenance. Compared to other compensators I’ve used that utilize more robust attachment methods, the EXOS-515 felt like a significant step down in terms of long-term reliability. I’ve used other comps from Strike Industries and Griffin Armament which have proven far more robust in hard use, though at a higher price point.
Breaking Down the Features of Faxon Firearms EXOS-515 Pistol Compensator for SIG P320
Specifications
The Faxon Firearms EXOS-515 Pistol Compensator for SIG P320 is constructed from 6061 aluminum with a black anodized finish. It features a single-port design with angled front ports intended to reduce muzzle climb. It is chambered for .355 caliber projectiles.
The EXOS-515 has 1/2×28 threads per inch and is designed for the SIG Sauer P320 platform. The compensator has a length of 1.4 inches, a width of 1.1 inches, and a height of 1.4 inches, adding minimal bulk to the pistol. Weighing in at just 0.8 lb, it keeps the pistol relatively lightweight. These specifications are aimed at providing recoil reduction without significantly altering the pistol’s balance or handling.
Performance & Functionality
The Faxon Firearms EXOS-515 Pistol Compensator for SIG P320 offers a slight reduction in muzzle climb compared to a non-compensated pistol. This reduction helps get sights back on target for faster follow-up shots. However, the issue with the loosening set screws significantly detracts from its overall functionality.
The design is aesthetically pleasing and integrates well with the SIG P320’s profile. But the compensator’s overall performance is hampered by the unreliable attachment method. This crucial flaw makes it difficult to recommend for serious use.
Design & Ergonomics
The EXOS-515 is lightweight and doesn’t drastically alter the pistol’s balance. The sleek design complements the SIG P320’s aesthetics. Installation is relatively straightforward, though it requires careful attention to the thread locker application and set screw torquing.
The lightweight aluminum construction is comfortable for prolonged use, but ultimately the ergonomic benefits are overshadowed by the reliability concerns. The constant need to check and re-tighten the screws is a frustrating distraction during shooting sessions.
Durability & Maintenance
The 6061 aluminum construction is adequate for range use, but may not withstand the rigors of heavy duty or tactical applications. The anodized finish is susceptible to wear and tear from repeated exposure to high-pressure gases. While cleaning is easy, the frequent need to re-tighten the set screws is a recurring maintenance issue.
The long-term durability of the EXOS-515 is questionable, especially compared to steel compensators with more robust attachment mechanisms. While the materials are adequate, the design’s reliance on set screws proves to be its Achilles’ heel.
Accessories and Customization Options
The Faxon Firearms EXOS-515 Pistol Compensator for SIG P320 includes thread locker, two 6-32 set screws, and a 1/16 Allen wrench. There are no additional accessories or customization options available directly from Faxon Firearms for this specific compensator. It is compatible with any SIG P320 barrel threaded to 1/2×28, which is a common thread pitch.
While the EXOS-515 doesn’t offer extensive customization, its compatibility with standard threaded barrels allows users to explore other aftermarket options. However, the limited accessories included with the product underscore its basic, no-frills design.

Who Should Buy Faxon Firearms EXOS-515 Pistol Compensator for SIG P320?
The Faxon Firearms EXOS-515 Pistol Compensator for SIG P320 might be suitable for casual range shooters seeking a budget-friendly compensator for minimal recoil reduction. It could also be a good option for shooters who prioritize a lightweight design and are willing to tolerate frequent maintenance.
This product is not recommended for serious competitive shooters, law enforcement personnel, or anyone requiring a highly reliable and durable compensator. Users who prioritize performance and reliability should consider investing in a more robust option with a secure attachment mechanism.

Conclusion on Faxon Firearms EXOS-515 Pistol Compensator for SIG P320
The Faxon Firearms EXOS-515 Pistol Compensator for SIG P320 presents a mixed bag of features and performance. While it offers a slight reduction in muzzle climb and boasts a lightweight, aesthetically pleasing design, its critical flaw lies in the unreliable set screw attachment method. The constant need to re-tighten the screws overshadows any potential benefits.
The price may seem justified for a basic compensator, but the lack of reliability makes it a questionable value proposition. Ultimately, I cannot confidently recommend this product. Shooters seeking a reliable and durable compensator should consider investing in a higher-quality option.
Therefore, while the EXOS-515 shows promise on paper, its real-world performance falls short of expectations. Save your money and explore other options if you’re serious about recoil management.
