Sig Sauer P365 XMACRO

The Sig Sauer P365-XMACRO is the full-grip version of the best-selling P365: a 3.7-inch slide, a frame long enough for every finger, and a 1913 rail, at one inch wide. It comes in four configurations — standard, COMP with an integrated compensator, TACOPS with a flared magwell, and factory Romeo-X optic packages — and every one we sell to New Jersey ships in a 10-round version. Prices run from about $780 for the base model to around $1,260 with the optic installed. Everything in stock is listed below.

Buying in New Jersey: the XMACRO ships to New Jersey buyers with two 10-round magazines and is otherwise identical to the 17-round gun. You need a Permit to Purchase for each handgun; we walk customers through it every week. Out-of-state buyers order the 17-round version and we ship to your FFL.

Which XMACRO?

Same frame, same slide length, same trigger. The differences are what sits on the front of the slide and what comes in the box.

Sig Sauer P365-XMACRO 9mm pistol, 10-round New Jersey version

Standard

P365-XMACRO

The baseline: 3.7-inch barrel, XRAY3 day/night sights, optics-ready slide, 1913 rail, interchangeable backstraps. The one to buy if you want the platform without paying for a compensator or an optic you may not use.

Sig Sauer P365-XMACRO COMP 9mm pistol with Romeo-X optic, 10-round version

Compensated

P365-XMACRO COMP

A 3.1-inch barrel with an integrated compensator built into the slide, so the overall length stays at 3.7 inches while muzzle rise drops noticeably. The flattest-shooting P365 made. Costs a little velocity and adds some flash in low light.

Competition and duty

P365-XMACRO TACOPS

The standard 3.7-inch barrel with a flared magwell and four magazines in the box instead of two. Built for people who reload under a timer. The magwell makes it slightly harder to conceal and it is the least carry-oriented of the four.

XMACRO with Romeo-X

Standard or COMP with Sig’s Romeo-X Compact red dot mounted and zeroed from the factory. Costs less than buying the optic separately and skips the plate-and-screws project. If you already know you want a dot, start here.

Common questions

What is the difference between the P365-XMACRO and the P365 XL?

Grip length and the rail. The XL uses the mid-length grip module and holds 12 rounds standard; the XMACRO grip is longer, holds 17 standard, and adds a 1913 accessory rail for a light. Slide length is the same 3.7 inches on both. In New Jersey both are 10-round guns, so the practical difference is the longer grip and the rail.

Is the XMACRO COMP worth the extra money?

If you shoot fast strings or you are recoil-sensitive, yes — the integrated compensator noticeably flattens the gun and it is the most shootable P365 Sig makes. If you mostly carry and shoot at a moderate pace, the standard XMACRO does everything you need for less. The comp also adds muzzle flash in low light, which some carriers dislike.

Do P365 magazines fit the XMACRO?

Standard P365 and P365 XL magazines are too short for the XMACRO grip and will not lock in. The XMACRO uses its own 17-round magazine (10-round in New Jersey). XMACRO magazines will work in the shorter P365 grips but will extend below the frame.

Can I buy the 17-round XMACRO in New Jersey?

No. New Jersey's magazine limit is 10 rounds and it remains in force — a federal appeals court struck it down in July 2026 and stayed its own ruling in August. The pistol itself is legal here in the 10-round configuration, which is what we sell to New Jersey buyers.

Does the XMACRO fit P365 holsters?

Usually not. Most P365 and P365 XL holsters are moulded for the shorter slide or lack a rail cutout. Holsters specifically listed for the XMACRO, or for the P365 XL with rail, are the ones to look for. We stock several; ask at the counter or check the holsters category.
