The Sig Sauer P365X 9mm with ROMEO Zero 3.1" slide in Coyote is a compact, sight-ready handgun built for shooters who want modern optics without the bulk. This complete slide assembly arrives fully outfitted with a factory-installed ROMEO-X COMPACT reflex sight and X-RAY3 day/night iron sights—a combination that lets you shoot with absolute co-witness using standard-height sights. No suppressor-height sight hassles, no adapter plates. It's a drop-in solution for P365 platform users ready to upgrade to a pistol-mounted red dot.
The 3.1" barrel keeps the P365X in the subcompact class, ideal for everyday carry, backup duty, or close-quarters home defense. Coyote Cerakote on stainless steel gives you a durable finish that handles hard use and stands out on the range. The ROMEO-X COMPACT optic uses a 2 MOA center dot with a 32 MOA circle—fast to acquire, easy to manage in bright sun or low light, and compact enough to maintain the gun's snappy profile. The X-RAY3 tritium/photoluminescent sights mean you're never left without a sight picture, even if the optic fails or the battery dies.
This is a complete upper: slide, internal parts, sights, and optic all installed. You'll need to source a P365 or P365X 3.1" barrel and recoil spring assembly separately—they're standard P365 parts and swap in without drama. Whether you're upgrading from iron sights or building out a second P365 platform gun, the P365X 9mm X-RAY3 ROMEO Zero slide gives you pro-level ergonomics and reliability in a package that fits your hand and your holster.
