The SIG Sauer P365X is a micro-compact 9mm designed for concealed carry. It combines the proven P365 fire control group with an optics-ready XSeries slide and a longer grip module for improved control. Since we added it to our lineup in late 2024, it has consistently been a top seller for its balance of size and shootability.

Frequently Asked Questions
What is the difference between the P365 and the P365X?
The P365X uses the standard P365 fire control group but features an optics-ready slide and a longer XSeries grip module. This provides better grip and immediate optic mounting capability without needing a separate adapter plate.
Is the weight noticeable when carrying?
Our staff notes the weight is barely noticeable once installed. At 6.4 ounces, it adds under an ounce of carry weight compared to the standard model, making no practical difference in comfort or concealment.
What optics fit the P365X slide?
The slide is cut for the SIG Sauer ROMEOZero and Shield RMSc footprints. This includes popular micro red dots like the Holosun HS407K and HS507K, which mount directly with no adapter plate required.
