First Impressions of SIG SAUER P320 Rear Sight Assembly
The SIG SAUER P320 Rear Sight Assembly is a critical component for anyone looking to maintain or upgrade the accuracy of their P320 pistol. SIG SAUER, renowned for their quality firearms and accessories, delivers a product promising reliability and straightforward installation. I remember the frustration of dealing with a drifting rear sight on a previous pistol, and I’m hoping this assembly will provide a solid, stable aiming solution for my P320.
I decided to purchase the SIG SAUER P320 Rear Sight Assembly because the factory sight on my P320 was damaged during a recent training course. The original sight lost its tritium insert, significantly impacting low-light visibility, so a replacement was a necessity. My options included aftermarket sights from various manufacturers, but I ultimately chose the SIG SAUER original equipment manufacturer (OEM) part, prioritizing guaranteed compatibility and factory-spec performance.
The SIG SAUER P320 Rear Sight Assembly arrived in a simple, functional package. Upon opening it, I immediately noted the robust construction of the sight plate and the clearly marked X-RAY3 tritium inserts. The weight felt substantial, indicative of quality materials, and the black finish appeared even and durable.
Compared to aftermarket options from Trijicon or Ameriglo, the SIG SAUER sight emphasizes maintaining the original P320 aesthetic and performance. While aftermarket sights often offer enhanced features like fiber optic inserts or different sight profiles, I preferred the assurance of factory compatibility and the consistent performance that comes with an OEM part. I chose this over others because I valued reliability above all else.
My initial impression was positive. The SIG SAUER P320 Rear Sight Assembly exuded quality and appeared to be a well-made, durable component. I felt confident that it would provide a reliable and accurate aiming solution for my P320.
Real-World Testing: Putting SIG SAUER P320 Rear Sight Assembly to the Test
First Use Experience
I first tested the SIG SAUER P320 Rear Sight Assembly at my local shooting range. Installation was surprisingly easy using a sight pusher tool, though I could see it being done with a punch and hammer, if necessary. The sight was immediately effective improving my grouping at 15 yards during initial accuracy tests.
The sight performed admirably in various lighting conditions. The X-RAY3 tritium inserts provided excellent visibility in low light, while the blacked-out rear sight body minimized glare in bright sunlight. I did not experience any issues with the sight shifting or loosening during the shooting session.
The installation was fairly straightforward, and the sight aligned perfectly with the existing front sight. I needed only minor adjustments to windage to achieve zero. No significant issues were encountered during the initial use.

After several months of regular use, the SIG SAUER P320 Rear Sight Assembly has proven to be a reliable and durable upgrade. It has maintained its zero through hundreds of rounds and various weather conditions. The sight still looks and functions as it did on day one, showing no signs of degradation.
The SIG SAUER P320 Rear Sight Assembly has shown no signs of wear and tear beyond minor surface scratches from holster use. Cleaning is simple: a quick wipe-down with a CLP-soaked cloth after each range session. This sight significantly outperforms the factory sight it replaced in terms of visibility and stability.
