SIG SAUER P320 X-Compact/Subcompact Threaded Pistol Barrel, 9mm Luger Review

First Impressions of SIG SAUER P320 X-Compact/Subcompact Threaded Pistol Barrel, 9mm Luger

For over a decade, I’ve lived and breathed tactical gear, from outfitting search and rescue teams to advising competitive shooters on their setups. When I heard SIG SAUER was offering a threaded barrel for the P320 X-Compact and Subcompact, I knew I had to get my hands on one. My interest piqued, this upgrade promised enhanced versatility, opening doors for suppressors and compensators to tame the snappy 9mm cartridge in a smaller platform.

I was looking to add another layer of utility to my P320 X-Compact, specifically the ability to run a suppressor. Living in a more populated area, reducing the noise signature at the range became increasingly important, not just for my own comfort, but for those around me. I had considered aftermarket barrels before, but reliability and maintaining the SIG SAUER reputation for quality were paramount.

The barrel arrived in a simple, no-frills package, exactly what I expected from a functional component. Lifting it out of the box, the immediate impression was one of solid construction and clean machining. The black Nitron finish appeared flawless and the threading was crisp and precise, a stark contrast to some of the cheaper, less reputable threaded barrels I’ve seen.

Several aftermarket barrels were available for the P320, some even at a lower price point. I opted for the SIG SAUER version, believing in their commitment to quality control and the assurance of perfect compatibility with my existing slide. Aftermarket options can be hit or miss, and I wasn’t willing to gamble on a critical component like a barrel, especially considering my experiences with some questionable barrels from other manufacturers over the years.

My initial reaction was excitement mixed with cautious optimism. While the barrel looked fantastic and felt robust, the real test would be how it performed on the range, cycling rounds reliably and maintaining acceptable accuracy. I was particularly interested to see if there would be any noticeable changes in the pistol’s balance or recoil characteristics with the added weight of a suppressor.

Real-World Testing: Putting SIG SAUER P320 X-Compact/Subcompact Threaded Pistol Barrel, 9mm Luger to the Test

First Use Experience

My first outing with the SIG SAUER P320 X-Compact/Subcompact Threaded Pistol Barrel, 9mm Luger was at my local outdoor range, a familiar setting where I could focus on evaluating performance. The weather was clear and mild, ideal conditions for testing both accuracy and suppressor compatibility. I brought along a variety of 9mm ammunition, ranging from standard 115-grain FMJ to heavier 147-grain subsonic rounds.

The barrel installation was straightforward, requiring only a few minutes using the standard P320 disassembly procedure. With the suppressor attached, the added length and weight were noticeable, but the pistol still felt manageable and well-balanced. The initial magazine through was encouraging: no failures to feed, extract, or eject, and the pistol cycled smoothly.

I was immediately impressed with the suppressed sound signature, a significant reduction compared to shooting without a suppressor. However, after about 50 rounds, I noticed a slight shift in the point of impact, a common occurrence when adding a suppressor, requiring a minor adjustment to my optic. After confirming that there were no obvious alignment issues with the suppressor, I took it as the cost of doing business and did not negatively affect the testing.

Extended Use & Reliability

After several months of regular use, the SIG SAUER P320 X-Compact/Subcompact Threaded Pistol Barrel, 9mm Luger has proven to be incredibly reliable. I’ve put several hundred rounds through it, both suppressed and unsuppressed, without a single malfunction directly attributable to the barrel itself. The Nitron finish still looks pristine, showing minimal wear even after repeated cleaning and handling.

The barrel has held up remarkably well, showing no signs of excessive wear or damage. Regular cleaning is simple and straightforward, and the Nitron finish makes it easy to wipe away powder residue and carbon buildup. Periodic lubrication is all that’s needed to keep it running smoothly.

Compared to some aftermarket barrels I’ve used in the past, the SIG SAUER barrel is in a different league. The consistency and reliability are unmatched, and the peace of mind knowing I’m using a SIG SAUER manufactured component is invaluable. It outperforms every other barrel I’ve used in a polymer framed pistol.
