Description
SIG Sauer P365X 9mm Pistol, 3.1" Barrel, 12-Round
The SIG P365X is the short-slide P365 with the longer X-series grip. You get the original 3.1 in. slide with a grip you can actually fill, and an optic-ready Nitron slide.
The optic cut is compact Shield RMSc. XRAY3 sights stay on the gun. The rail is SIG’s P365 rail, not 1913. The slide is not compensated. A factory red dot is installed only when this page says so. These pistols ship to a licensed FFL.
This configuration
That layout is the whole pitch. More grip than a standard P365, shorter than a P365 XL, and not an XMacro: no 17-round flush mag, no 1913 rail, no interchangeable backstraps. The slide is compact Shield RMSc optic-ready with XRAY3 sights and a rear sight plate. No factory red dot. The rail is SIG’s P365 rail, not 1913. The slide is not compensated.
What ships
A factory optic is installed only when this page says so. This item ships to a licensed FFL. See the SIG P365X collection.
