The Sig Sauer P365 Fuse Comp pistol in 9mm with a 3.7-inch barrel and factory-installed ROMEO-X optic (brand part no. 365XF-9-COMP-RXSL) pairs an integrated slide compensator with a fully enclosed, sealed, and gas-purged red dot mounted using Sig’s SIG-LOC system for the strongest lockup in the industry. Sig Sauer mounts the optic from underneath the slide with a side battery, keeping deck height low while still co-witnessing with standard-height iron sights. X-Ray3 day/night sights back up the optic, and one 17-round plus two 21-round steel magazines ship with the pistol. Among factory-optic compensated semi-auto handguns, this P365 Fuse Comp configuration favors shooters who want a complete, optic-equipped compensated package.
