The Sig Sauer P365X-Macro TACOPS pistol in 9mm Luger with a 4.3-inch barrel and factory ROMEO-X optic (brand part no. 365XCA-9-BTAC-TB-RXSL) delivers the largest-capacity P365 configuration, pairing a slide-mounted red dot with a substantial 21-round magazine. Sig Sauer cuts the serrated slide with an optic mount for the pre-installed ROMEO-X, and tritium night sights back up the optic for reliable low-light aiming. The TACOPS designation marks this configuration’s tactical-oriented build, and four 21-round steel magazines are included, giving shooters a deep ammunition reserve. Among high-capacity semi-auto handguns, this P365X-Macro TACOPS configuration favors shooters who want maximum P365-platform capacity with a factory optic.
