Detailed Features 

The XMacro is the higher-capacity variant in the P365 family, using a wider grip module to fit the 17-round magazine without adding much length or height. XRAY3 sights use tritium inserts in a day/night configuration for reliable low-light use. The RMS/SMS optic cut allows direct mounting of compatible miniature red dots. Interchangeable backstraps adjust grip circumference to fit different hand sizes. The manual thumb safety is standard on this variant. At 22 oz, it runs heavier than the base P365 but lighter than most full-size pistols at this capacity level.

The P365 XMacro receives generally positive feedback, with the 17+1 capacity in a compact footprint as the main appeal.

Owners frequently cite the capacity as the reason they chose the XMacro over the base P365. The additional rounds without a significant size penalty is the defining feature of the platform. The XRAY3 sights get consistent positive mentions for low-light visibility, and the compact dimensions are noted as carrying well under most everyday clothing. Range performance including accuracy and reliability across ammunition types is broadly well regarded.

The trigger draws divided opinions. Some find it smooth enough for both range and defensive use; others note the pull feels heavier than competitors and would prefer a lighter or shorter-resetting trigger for rapid fire. The grip runs slightly wider than the base P365, which some buyers find marginally bulkier for deep concealment. Magazine pricing and availability for extra mags comes up occasionally as a friction point. The price is debated as reasonable by some and elevated by others when compared against full-size options with similar round counts.
