The SIG P365X MACRO 9mm 3.7" XRAY3 from Sig Sauer brings the P365 series into a high-capacity, optics-ready platform that suits concealed carry, duty use, and range work with confident ergonomics and modern features; the polymer frame in black with Nitron-finished slide keeps weight at a manageable 22 ounces while delivering a 3.7-inch barrel and a 17-round magazine capacity for extended firepower in a compact footprint. The MACRO model builds on the proven P365 family by widening the grip to accept full-size capacity without sacrificing concealability, pairing XRAY3 night sights for low-light target acquisition with an optics footprint that accepts Shield/RMSC-style red dots for faster sight picture acquisition on the street or the range. Semi-auto operation and reliable Sig engineering make follow-up shots controllable, while the polymer grip texture and intuitive controls support consistent handling under stress; the slide and frame finish resist wear from holstering and regular use. This is a licensed firearm sale requiring FFL transfer, and the P365X MACRO is a strong option for shooters seeking a high-capacity micro-compact 9mm handgun that is optics-ready and built for everyday carry and defensive applications.
