Ballistic Advantage SIG P365 XL/X Marco Non-Fluted Threaded Pistol Barrel w/o LCI Review

First Impressions of Ballistic Advantage SIG P365 XL/X Marco Non-Fluted Threaded Pistol Barrel w/o LCI

As an outdoor and tactical gear specialist with over a decade of experience, I’ve seen countless firearms and components come and go. But I was particularly intrigued by the Ballistic Advantage SIG P365 XL/X Marco Non-Fluted Threaded Pistol Barrel w/o LCI. Ballistic Advantage has a reputation for producing high-quality AR barrels, and I was curious to see if they could translate that expertise into the handgun market, specifically for the extremely popular SIG P365 platform.

My SIG P365 XL has become my go-to concealed carry weapon, but I was looking to enhance its performance and versatility. I wanted the ability to add a compensator for improved recoil management and faster follow-up shots. Thus, a threaded barrel was a must.

When the barrel arrived, I was immediately impressed by its appearance. The stainless steel had a clean, almost polished look, and the threads were precisely cut. Compared to the stock SIG barrel, this Ballistic Advantage barrel felt more substantial and refined. I had also considered barrels from Faxon and True Precision, but Ballistic Advantage’s reputation for accuracy, combined with the competitive price point of $156.75, ultimately swayed my decision. My initial impression was one of excitement and anticipation. I was eager to get to the range and see how it performed.

Real-World Testing: Putting Ballistic Advantage SIG P365 XL/X Marco Non-Fluted Threaded Pistol Barrel w/o LCI to the Test

First Use Experience

My first outing with the Ballistic Advantage SIG P365 XL/X Marco Non-Fluted Threaded Pistol Barrel w/o LCI was at my local outdoor shooting range. The weather was typical for late spring – slightly humid with a light breeze. I brought along a variety of 9mm ammunition to test compatibility and accuracy.

Installation was relatively straightforward, although, as noted in some user feedback, the fit was extremely tight. The first few attempts to rack the slide were met with significant resistance, causing me some initial concern. After about 20-30 cycles and some lubrication, the action smoothed out considerably. During the initial 50 rounds, I experienced two failures to fully return to battery, likely due to the tight tolerances.

Extended Use & Reliability

After the initial break-in period, the Ballistic Advantage barrel has proven to be remarkably reliable. I’ve now put approximately 500 rounds through it, ranging from standard 115-grain FMJ to 124-grain +P hollow points, and I’ve experienced no further malfunctions. The PVD finish shows minimal signs of wear, even after repeated holster draws.

Cleaning is simple, requiring only standard solvents and brushes. I’ve noticed no significant fouling or carbon buildup. Compared to my experience with other aftermarket barrels, the Ballistic Advantage barrel has exceeded my expectations in terms of reliability and durability. The improved accuracy, especially when using a compensator, is also noticeable.
