I’d been searching for a barrel upgrade that would increase the longevity of my P365, without sacrificing its concealability.

The Norsso barrel’s reputation for quality materials and improved chamber support caught my eye.
Upon unboxing, the Norsso barrel immediately impressed me. The satin stainless steel finish was smooth and even, devoid of any tool marks or imperfections. The weight, though negligible compared to the stock barrel, felt solid and indicative of quality materials.

Real-World Testing: Putting Norsso N365 3.1in Barrel for SIG Sauer P365, 9mm to the Test
First Use Experience
My initial testing took place at my local outdoor range, where I put the Norsso barrel through its paces with a variety of 9mm ammunition, ranging from standard 115-grain FMJ to 124-grain +P hollow points. I wanted to see how it handled different loads. The weather was slightly damp, adding a touch of real-world challenge.
The Norsso barrel performed flawlessly, exhibiting consistent accuracy and reliable cycling. I noticed no discernible difference in felt recoil, but the overall shooting experience felt smoother. The absence of an LCI slot, while not directly impacting performance, provided a cleaner, more streamlined aesthetic.
Installation was straightforward, a true drop-in replacement requiring no gunsmithing. After the first 100 rounds, I noted a slightly tighter lockup, which contributed to the improved consistency. There were no malfunctions or issues, which was a pleasant surprise given some aftermarket parts can sometimes be finicky.
Extended Use & Reliability
After several months and approximately 1,000 rounds, the Norsso barrel has held up exceptionally well. There are no signs of abnormal wear or tear on the finish or the rifling. I inspect it thoroughly after each range session.
Cleaning and maintenance have been simple, requiring only standard lubrication and bore cleaning after each use. The stainless steel construction resists corrosion, even after extended periods of storage. I was extremely impressed that it cleaned up so quickly.
Compared to my previous experiences with other aftermarket barrels, the Norsso has been significantly more reliable. I have not experienced any failures to feed, extract, or eject. The enhanced chamber support gives me confidence when using +P ammunition, something I was hesitant to do with the factory barrel.
