SIG P365 Pistols

The SIG P365 is SIG’s original micro-compact 9mm. A 3.1 in. barrel sits in a slim polymer grip. Overall length is 5.8 in. XRAY3 day/night sights sit on the optic-ready 9mm slides. The rail is SIG’s P365 rail. The .380 is that same size with a slide that is easier to rack and P365 .380 magazines. ROSE, FLUX, DH3, AXG LUXE, and dealer finishes live on this page. P365X, XL, XMacro, Fuse, and AXG Legion stretch the idea with more grip or more slide and live on their own pages. Handguns ship to a licensed FFL.

A factory red dot is installed only on the pistols that list one. Ten-round magazines ship with the restricted-capacity pistols. See SIG P365X, SIG P365 XL, SIG P365 XMacro, XMacro Comp, Fuse, and AXG Legion.

How to choose

Original 3.1 in. 9mm is the classic P365. The .380 is the easier-racking P365 in .380 ACP. ROSE is the factory ROSE package on that .380, with rose-gold controls and a Vaultek LifePod. FLUX is a chassis around the P365 fire control unit, with a 6 in. barrel and a spring-deployed brace. DH3 is the AXG-frame ported 3.7 in. gun. AXG LUXE is the metal-frame compensated .380. TACOPS dealer pistols add a 17-round grip. The XMACRO Kit is a 3.7 in. XMACRO with 10-round magazines and a Vaultek certificate.

Frequently Asked Questions

What is a SIG P365?

The SIG P365 is SIG’s original micro-compact 9mm. A 3.1 in. barrel sits in a slim grip. Larger P365s such as XL, XMacro, Fuse, and AXG Legion live on their own family pages.

What is the difference between a P365 9mm and a P365 .380?

Both use the original P365 size. The .380 is chambered in .380 ACP and uses .380 magazines. Those magazines are not interchangeable with the 9mm P365.

Is the original P365 optic-ready?

These original-size P365s are optic-ready on a compact Shield RMSc cut unless the page installs a factory sight. SIG-LOC Compact is not a drop-in RMSc plate.

What is a P365-FLUX?

FLUX is a chassis around a P365 fire control unit, with a 6 in. barrel, a muzzle shroud, and a spring-deployed brace. Barrel and magazines follow that chassis.

Does a P365 ship to my door?

Handguns ship to a licensed FFL for transfer.
