  P365 MACRO: Bridging the Gap Between Compact and Full-Sized Pistols

  The P365 MACRO is not just a bigger version of the original P365—it is a reinvention. SIG SAUER has engineered a compact handgun that delivers 17-round magazine capacity in a slim-profile frame—something previously unheard of in the concealed carry world.

  Unlike most subcompacts that require compromises in grip length, controllability, or accessory compatibility, the MACRO design integrates a full-length grip, optic-ready slide, enhanced ergonomics, and integrated compensator to mitigate recoil. The result is a sidearm that behaves like a full-size pistol in your hands but remains concealable under a T-shirt.

  Performance Meets Practicality: Built for Everyday Defense

  The 3.7” barrel offers an optimal balance between compactness and performance. It delivers increased muzzle velocity and accuracy over smaller barrels, while maintaining a footprint suitable for appendix or waistband carry. Its integrated compensator aids in reducing muzzle flip, allowing for faster follow-up shots—crucial in high-stress defensive scenarios.

  Whether you’re training on the range or carrying daily, you’ll notice how confidently the P365 MACRO handles recoil, tracks on target, and fits into your holster.

  ---

  Ergonomics and Feel: Made for Real-World Hands

  Unlike traditional compacts that can feel cramped or unsteady in larger hands, the P365 MACRO’s grip is a game changer. The extended grip module accommodates all fingers for a secure hold while retaining a slim 1.1” width. The aggressive stippling ensures a confident, non-slip grip in wet, sweaty, or gloved conditions.

  Additionally, the P365 MACRO is fully modular, compatible with SIG’s P365 Fire Control Unit (FCU) system. This gives shooters freedom to customize their configuration or swap frames, slides, and barrels according to preference.

  ---

  17+1 Capacity: No Compromise on Firepower

  One of the standout features of the P365 MACRO is its industry-defying 17-round capacity in a pistol smaller than most compacts. Traditionally, such capacity was reserved for full-size duty pistols. With this offering, SIG SAUER rewrites the rulebook, empowering carriers with more rounds in the fight—without sacrificing size or weight.

  Compared to typical micro-compacts (which often carry 10–13 rounds), the MACRO gives you a significant advantage, especially in self-defense situations where capacity can mean survival.

  ---

  Sights and Optics: Prepared for Any Condition

  The pistol comes standard with SIG SAUER’s XRAY3 Day/Night Sights—a premium three-dot tritium system designed for superior visibility in low-light conditions. These combat-grade sights are fast to acquire and reliable in all lighting environments, from bright daylight to total darkness.

  In addition, the slide is optics-ready, pre-cut for RMSc or ROMEOZero red dot sights, enabling faster target acquisition and expanded situational awareness for modern shooters who prefer optics over irons.

  ---

  Trigger System: Flat, Fast, and Crisp

  The P365 MACRO comes equipped with a flat-faced trigger, providing a consistent, clean break and a short reset. The flat design promotes a natural index, improved control, and better accuracy, especially when shooting rapidly or under pressure.

  This trigger, combined with the MACRO’s compensated slide and grip geometry, allows shooters to make fast, accurate shots with confidence—making it a joy on the range and a trusted companion in the field.

  ---

  Concealed Carry Compatibility

  Despite its full-length grip and expanded magazine, the P365 MACRO remains highly concealable. The pistol is only 1.1” wide and has a 5.2” height—comparable to smaller pistols that offer much less in terms of capacity or control.

  It’s designed for IWB (inside the waistband), appendix, or OWB (outside the waistband) carry, with a vast array of holster compatibility from leading brands. You can carry it daily without discomfort or printing, even with light clothing.

  ---

  Accessory Ready: Tactical Versatility

  Outfitted with a standard 1913 Picatinny rail, the P365 MACRO allows you to mount tactical accessories like lights, lasers, or combinations—making it suitable for both civilian EDC and professional use (LEO, security, tactical applications).

  This rail makes it much more flexible than most micro-compacts, which use proprietary rail systems or none at all.

  ---

  Durability and Finish

  The Nitron-coated stainless steel slide offers enhanced corrosion resistance and durability, ideal for those carrying in humid climates or high-contact environments. The polymer frame is rugged and tested under real-world conditions.

  This firearm is built to endure high round counts, rough use, and tough environments. SIG’s manufacturing quality ensures long-term reliability and smooth operation, even after thousands of rounds.

  Why Choose the SIG SAUER P365 MACRO?

  When choosing a concealed carry pistol, most users must compromise on one of the big three: capacity, controllability, or concealability. The P365 MACRO breaks this triangle and gives you all three in a single platform:

  • Firepower of a full-size with 17+1 rounds

  • Ergonomics and accuracy of a duty pistol

  • Size and concealability of a compact

  Whether you’re an armed professional, a first-time carrier, or an experienced shooter, the P365 MACRO delivers unmatched performance, reliability, and adaptability.

  The P365 MACRO wins on capacity and concealability without compromising capability.
