The Sig Sauer P365 Fuse Comp 9mm pairs a slide-integrated compensator with a factory-mounted ROMEO-X SIG-LOC optic (Sig Sauer part no. 365XF-9-COMP-RXSL). Sig Sauer builds it on a polymer grip module with a 3.7-inch barrel and a 21+1 capacity, so it carries easily and shoots like a full-size pistol. The expansion chamber in the slide helps reduce muzzle rise without adding length. X-Ray3 day and night sights allow a co-witness through the optic window. It is a modern carry and range pistol for shooters who want a red dot and a comp straight from the box.
