The P365 XL extends the P365 platform with a longer 3.7-inch barrel, taller slide profile, and extended grip module that accommodates a 12-round flush magazine. The flat X-Series trigger and optics-ready slide were standard from launch — the XL was the first P365 to offer a Romeo Zero optic-ready configuration out of the box. It splits the difference between the original P365 and the P365 X-Macro in terms of size and capacity, and is widely considered the optimal balance in the P365 family.
