Sig SauerRomeo-X SIG-Lock Compact Red Dot Sight - Rugged Durable Aluminum Lightweight Waterproof MOTAC Fully Enclosed Reflex Sight with 15 Illumination Settings

This fit perfectly and didn’t need much adjustment at all to get zero with it. They are starting to release more slides for the P365 that are cut for the SIG-LOC. My AXG Legion is from April 23, 2025. But make sure your can take this and the slide is SIG-LOC compatible or it wont fit on the slide.

I got this to replace the Romeo-X Compact Open Refelex Sight that came with my P365 Fuse. I upgraded mostly because of how annoying it became having to constantly clean dust and debris from inside of the lens. Im glad I did because this enclosed version is great. It has everything I was looking for like cowitnessing with the irons, multiple reticles, easy to zero, and ease of mounting with the new SIG LOC pattern. All the reticles are bright and easy to see even with my astigmatism. To my knowledge, the P365 Fuse is the only slide with the ability to use the SIG LOC pattern. So verify that your slide can use SIG LOC before purchase.

Great product. Sturdy and durable. Holds zero (so far) and easy to adjust.
