SIG P365 X-MACRO: It’s a 17+1. Here are the details By: David Reeder


As many of you have already heard (and more are about to), SIG Sauer has released another hybrid compact pistol in the SIG P365 line — like its predecessors, the “SIG P365 X-Macro” has just a 1″ profile. But this one has a 17 round capacity P365X magazine.

Shooting the P365 XMacro

This might not be as big a surprise as the original P365s were for their capacity, but that’s likely because we’ve at least partially become inured to rapid advances in small frame pistol design. That doesn’t make it any less a desirable evolution in the P365, though, particularly when you consider that same mag will fit in the P365 model you already own.

P365 XMacro Specs

The P365-XMacro is a polymer frame, striker-fired pistol that features a new grip module, the “Macro-Compact-Grip Module”. The Macro-Compact Grip Module features a standard 1913 accessory rail, an integrally compensated optics-ready slide with their XRAY3 day/night sights, and a flat trigger. The weapon ships with interchangeable small, medium, and large backstraps, and two 17 round P365 XMacro magazines. As one would expect, the pistol  is optimized for use with SIG electro-optic red dot sights and weapon lights.

Tom Taylor, SIG’s Chief Marketing Officer, had this to say about the new pistol:

“When the P365 was introduced, it reimagined the possibilities of everyday carry, and the P365-XMACRO continues this tradition delivering more on everything that made the P365 the number one selling, and most award-winning gun in America. 

“The innovative magazine design of the P365-XMACRO delivers on capacity while maintaining the slim design, making it more comfortable and more concealable than any other 17+1-round pistol on the market. The integrated compensator of the P365-XMACRO reduces muzzle flip making follow-up shots faster and easier to stay on target shot after shot for even more accuracy. It is very simple, like the name suggests, with the P365-XMACRO you get more of everything you want in an everyday carry pistol, and you no longer need to compromise your capacity for concealability or shootability.”

P365 XMacro First Looks

Aaron Cowan of Sage Dynamics recently posted these images to social media with the comment, “The 365 line has been growing on me, and now I have [one that is] 17-round capacity, optic-ready, with adjustable back straps and a more robust accessory rail.” 

He also notes that this gun does a good job of bridging the gap between “full size guns” and the micro compacts with high magazine capacity.

P365 XMacro Magazines

As noted, the P365 XMacro has a 17+1 round magazine potential before mag extensions. As John Hollister of Sig Sauer Academy said, “XMacro vs XL: same slide and thinness. You just get more. Twelve vs. seventeen.

Happily, that 17-round magazine can be used in any P365 pistol (assuming you already have one).

SIG P365 X-Macro FAQs

• Q: Will the new 17-round magazines fit in earlier P365 models?
