The Sig Sauer P365X is a striker-fired semi-automatic pistol chambered in 9mm Luger, built around a 3.1-inch barrel and a 10+1 capacity. At 18 oz it sits comfortably in concealed carry use without sacrificing much in the way of grip real estate.

Detailed Features 

The XSeries grip module is wider and longer than the standard P365 frame, which gives you more hand contact and better control without adding much bulk. XRAY3 day/night sights work well in low light without any optic attached. The optics-ready slide accepts the SIG ROMEOZero and other compatible micro red dots directly, no adapter needed. 
 

Usage 

The P365X is aimed at concealed carry users who want more capacity and a fuller grip than the base P365 offers. It works equally well as a home defense pistol or for range sessions where the extended grip pays off in comfort over a long string of fire.

User feedback on the P365X breaks down fairly predictably. The compact size paired with the 10+1 capacity is the most consistent positive across reviews -- shooters coming from single-stack guns appreciate the step up in round count without a meaningful increase in printing. The wider XSeries grip gets high marks from people with medium to large hands who found the base P365 a bit small.

The trigger divides opinion. Some shooters find the pull heavier than they'd like or describe it as not quite as crisp as competitors at the same price point. It's not a dealbreaker for most, but it comes up often enough to be worth noting.

Holster selection was an issue early on since the X-series frame didn't fit all standard P365 holsters, though availability has improved. Recoil with standard 9mm is manageable, but a handful of users running +P ammunition found it snappier than expected for a gun this size. Pricing is generally accepted as fair given the feature set, though some shoppers compare it unfavorably to other sub-compact options at lower price points.
