Sig Sauer P365 XMacro 9mm, 3.7 in Barrel, 17+1 Capacity, Optics-Ready, XRAY3 Sights, Black Nitron, USA
This Sig Sauer P365 XMacro stands out with its 17+1 capacity in a compact, XMacro-length grip module, a 3.7 in barrel in the non-Comp configuration, and a stainless-steel slide finished in black Nitron. It features an optics-ready slide with a removable cover plate, SIG XRAY3 day/night sights with a high-visibility green front dot, and a true 1913 dust-cover rail. It comes with the factory case, manuals, three magazines (two shorter P365/P365X magazines and one 17-round XMacro magazine), and additional grip modules and backstraps. Note: The included factory case label shows SKU 365X-9-BXR3P-MS (P365X with manual safety) matching the serialized FCU; the pistol has been reconfigured to the current XMacro, non-Comp, no‑manual‑safety configuration with a 3.7 in barrel and 17‑round magazine.
