Owners of the P365 X-Macro appreciate how much Sig Sauer packed into the package. The Romeo-X Compact optic and compensator come installed and co-witnessed out of the box, which removes the typical guesswork of aftermarket optic mounting. Most find the 3.1-inch barrel and compensator combination keeps muzzle flip tighter than a bare barrel of the same length.

The compact frame is a point of debate. Shooters who came from the original P365 find the X-Macro slightly thicker in the grip, which helps with control but reduces the pocket-carry advantage that made the P365 platform popular. For holster carry, the added width is generally accepted as a worthwhile trade for improved recoil management.

The 10+1 capacity limitation gets mentioned in nearly every review from buyers in standard-capacity states. Those who can access higher-capacity magazines often wish Sig included them at this price point. The XRAY3 sights are well-regarded as a fallback if the optic battery dies, and battery life rarely comes up as a complaint.
