SIG STORE HERITAGE PREMIUM PACKAGE: SIG Sauer P365 3.1\" Complete Slide w/ Radian Ramjet & ROMEO-X Compact Radian Ramjet Afterburner • OEM SIG P365 Slide • SIG SAUER ROMEO-X Compact Optic Assembled & Ready • Premium P365 Performance Package High-Value Build Summary OEM SIG Sauer P365 3.1\" complete slide assembly paired with a Radian Ramjet + Afterburner compensator system and SIG SAUER ROMEO-X Compact optic. This is a premium assembled package designed for buyers who want a complete, high-end P365 slide upgrade without sourcing each component separately.
This listing is for a premium SIG Sauer P365 3.1\" complete slide package built around some of the most desirable upgrades available for the P365 platform.
This setup combines an OEM SIG Sauer P365 complete slide with the Radian Ramjet + Afterburner compensator system and a SIG SAUER ROMEO-X Compact optic already installed.
The 3.1\" slide paired with the Ramjet Afterburner creates a profile that finishes close to P365XL / X-Macro length, giving the buyer a compact compensated configuration with a premium factory-style appearance.
This is the shorter and more compact configuration compared to the longer 3.7\" XL slide version. Many buyers prefer the 3.1\" setup because it preserves the original P365 slide size while adding the performance and visual presence of the Radian system.
