SIG P320 Pistols

The SIG P320 is SIG’s modular striker-fired pistol. The serialized part is the fire control unit. Compact, full-size, XCompact, XCarry, XFull, XFIVE, AXG, Spectre Comp, XTEN, FLUX, and MAX guns all hang different slides and grips on that same idea. M17 and M18 live on their own pages. Handguns ship to a licensed FFL.

A factory red dot is installed only when the product page says so. Ten-round guns are those magazine sets. See also SIG M17 and SIG M18.

How to choose

Compact and XCompact are the shorter 9mm guns. Full-size and XFull stretch the slide. XFIVE and MAX are the 5 in. guns. AXG is the metal grip. XTEN is 10mm, not 9mm. FLUX is a chassis, not a standard P320 grip. Fire control units are the serialized FCU, not a complete pistol.

Frequently Asked Questions

What is a SIG P320?

The SIG P320 is SIG’s modular striker-fired pistol. The fire control unit is the serialized part. Grip modules and slides change the size and caliber around that FCU.

What is the difference between P320 Compact and P320 Full-Size?

Compact uses a shorter slide and grip, commonly a 3.9 in. barrel. Full-size uses a longer slide, commonly 4.7 in. Magazines and holsters are not the same.

What is a P320 XTEN?

XTEN is the 10mm Auto P320. It is not a 9mm P320 with a different barrel. Magazines are 10mm XTEN magazines.

Is a P320 fire control unit a complete pistol?

No. A Custom Works FCU is the serialized fire control unit. You still need a grip module, slide, and magazines to have a complete pistol.

Does a P320 ship to my door?

No. Handguns and serialized fire-control units ship to a licensed FFL for transfer.
