SIG SAUER Pro P320 9mm Romeo X Pro XRAY3 Sights Barrel Assembly Review

First Impressions of SIG SAUER Pro P320 9mm Romeo X Pro XRAY3 Sights Barrel Assembly

The SIG SAUER Pro P320 9mm Romeo X Pro XRAY3 Sights Barrel Assembly promises a significant upgrade for P320 owners looking to enhance their pistol’s sighting system. Integrating a slide-mounted ROMEO-X PRO optic and XRAY3 iron sights, this assembly aims to provide a seamless and versatile aiming solution. SIG SAUER is a trusted name, and this product presents an opportunity to modernize my P320 without the need for extensive modifications.

I was looking for a pre-assembled slide that would allow me to add an optic to my P320 without the hassle of aftermarket milling or needing to purchase suppressor height sights. The promise of co-witnessing standard height sights with the ROMEO-X PRO was particularly appealing, streamlining the transition to red dot shooting. Upon unboxing, the slide assembly felt solid and well-made, a testament to SIG SAUER’s reputation for quality. The Nitron finish was smooth and even, while the optic appeared securely mounted. The weight felt balanced, suggesting good integration between the slide, optic, and sights.

Compared to purchasing a separate slide, optic, and sights, this pre-assembled package seemed like a convenient and cost-effective solution. I considered aftermarket slides with pre-cut optic mounts, but the factory SIG SAUER assembly offered peace of mind regarding compatibility and reliability. My initial impression was positive; the assembly appeared to be a well-thought-out upgrade that could significantly improve my P320’s performance. I was definitely excited to get it to the range.
