SIG Sauer P365-XMACRO 9mm Pistol: Full Review
In the world of concealed-carry handguns, few models combine capacity, control, and compactness quite like the Sig P365 X Macro Comp. Designed to pack “more” into an already popular platform, this pistol redefines what a micro-compact can offer. With a 17+1 round capacity, an integrated compensator, and a slim 1-inch profile, it aims to deliver full-size firepower without sacrificing concealability. In this detailed review, we'll dive into its specifications, design, performance, and practical carry implications.

Design
At the heart of this pistol’s design philosophy is “MACRO means MORE.” Sig Sauer has squeezed a full-size 17-round capacity into an ultra-slim, macro-compact frame — a design that stands out in its class. The slide is optic-ready, meaning it’s cut to accept popular red-dot footprints (Shield RMS-c) for fast target acquisition.
Its integrated compensator is built right into the slide, which helps tame muzzle rise and makes the gun more controllable, particularly in fast follow-up shots. The grip module is thoughtfully designed: interchangeable backstraps let you tailor the grip to your hand size, and a standard 1913 rail supports the attachment of lights or lasers.
Grip & Ergonomics
One of the biggest strengths of the P365 X Macro Comp is its ergonomics. The macro-compact grip module is wider than the original P365’s, which gives your hand more purchase while still maintaining a slim profile.
Interchangeable backstraps (small, medium, large) make it highly customizable. Whether you have smaller hands or prefer a more substantial grip, the option to configure the grip goes a long way in making the gun feel very natural.
The 1913 rail under the frame gives you real utility for mounting accessories. For a carry gun, that’s a definite plus.

Trigger
The trigger is flat-faced and striker-fired, which contributes to a clean and predictable pull. There is no manual safety on many versions, which reduces complexity but also places more emphasis on trigger discipline and safe handling.
The flat trigger can feel crisp under stress, and many shooters report good consistency in pull weight, helping with accuracy and shot control.
Recoil & Accuracy
Thanks to its built-in compensator, the P365 X Macro Comp handles recoil surprisingly well for a pistol of its size. The compensator helps divert gases upward, reducing muzzle flip and letting you stay on target for follow-up shots.
Coupled with its 3.1-inch barrel and stable grip, that leads to good accuracy in both controlled range fire and quick defensive drills. The XRAY3 day/night sights also enhance target acquisition in varied lighting conditions, making it reliable whether you're practicing or carrying.
Carry Use
Concealability
The gun’s slim 1.1-inch profile and relatively compact length make it well-suited for everyday carry, even for those prioritizing concealment.
Despite the high capacity, the design doesn’t sacrifice on portability — a major win for those who want more bullets in a discreet package.
Comfort
Interchangeable backstraps mean you can fine-tune the grip to your hand, helping with comfort during extended carry or when shooting.
The 1913 rail lets you add tactical accessories without bulky aftermarket modifications.
Control
The compensator significantly reduces felt recoil and muzzle rise, making it more controllable than many micro-compact pistols, which is especially valuable in high-stress or rapid-fire scenarios.
