Sig Sauer P365X ROMEO-X 9mm 3.1″ | 2x10rd | 365X-9-BXR3-RXX-10

The Sig Sauer P365X ROMEO‑X is a compact, optic‑equipped 9mm pistol built for everyday concealed carry and range training. It features a 3.1 inch barrel and an optic‑ready Nitron stainless slide with the Romeo‑X Compact red dot installed. The XSeries polymer grip module adds an integrated carry magwell and an extended beavertail for secure, repeatable presentation. For optics under $1,000, the factory‑installed SIG Romeo‑X Compact red dot pairs directly and preserves the P365X’s low‑profile footprint.
