Sig Sauer P365 FUSE TACOPS 9mm | Threaded Barrel | 365XF-9-CTAC-TB-RXSL

The Sig Sauer P365 FUSE TACOPS is an optic-ready variant of the P365 family built to combine high capacity and controllability in a slim grip package. It ships with a factory-mounted ROMEO‑X using the SIG‑LOC mounting system, XRAY3 day/night sights, a threaded barrel, a detachable magwell and four 21‑round steel magazines. The design emphasizes extended slide length and balance for improved sighting and follow-through while retaining the compact ergonomics of the P365 line. A Shield RMSc‑compatible reflex sight such as the Holosun 507K is a suitable optic choice under $1,000 for those who want a low-profile, rugged red dot on this platform.

Typical applications include everyday carry (EDC) where higher magazine capacity and concealability are prioritized, and range training or competition where the extended slide and larger magazine set improve sustained performance.
