Radian Afterburner + Ramjet P365 Combo Barrel

Premium Concealed Carry Performance

The Radian Afterburner + Ramjet combination delivers industry-leading recoil reduction and match-grade accuracy in a package designed for serious concealed carry shooters. This is a complete solution for those seeking to upgrade their Sig Sauer P365 or P365X with professional-grade components.

Design and Construction

Barrel: The Ramjet barrel is machined from hardened 416R stainless steel and enhanced with Radianite coating for exceptional durability.

Compensator: The Afterburner compensator is precision-machined from hardened stainless steel, also finished with Radianite coating. Angled front faces aid in smooth holstering.

Coating Technology: The Radianite finish achieves low friction, high hardness, and superior corrosion resistance—eliminating concerns about muzzle blast erosion and ensuring long-term reliability.

Installation and Compatibility

The threadless barrel design allows for effortless installation and removal without tools, making cleaning and maintenance straightforward. The INTRA-LOK mounting system uses a tapered locking screw that interfaces with an angled V-groove, ensuring perfect timing and repeatability every time.

When installed on a P365 or P365X, this combo increases overall slide length to P365XL dimensions, providing compatibility with all P365XL holsters.

Important Compatibility Note

This product is not compatible with Sig Sauer models featuring a loaded chamber indicator (LCI). The Ramjet barrel does not include an LCI cut and will not seat properly with the indicator in place.
