The Sig Sauer P365X is a micro-compact semi-automatic pistol chambered in 9mm Luger with a 3.1-inch steel barrel. It ships with a 12+1 capacity and a stainless steel optic-ready slide over a black polymer frame that includes an accessory rail. The striker-fired P365X uses the X-Series trigger and is built around Sig's micro-compact frame.

P365X owners frequently point to the optic-ready slide as the standout feature over the standard P365. Getting a red dot on a pistol this size without a gunsmith visit is the main draw, and most users report the footprint cuts are clean and solid.

The X-Series trigger is an upgrade most shooters notice immediately. Reset is shorter and the break is crisper than the base P365 trigger, though a small number of users find it slightly lighter than expected and prefer an aftermarket flat-faced option.

At the micro-compact size the 12+1 capacity gets regular praise. The common complaint is that the grip length leaves room for improvement during extended range sessions, though for its intended carry role most owners consider that an acceptable trade-off.
