The Radian AFTERBURNER + RAMJET is a precision-engineered performance upgrade for the SIG P365XL, designed to provide match-grade accuracy, enhanced recoil control, and refined aesthetics—all in a compact, carry-ready configuration.
The RAMJET is a fluted, black DLC-coated, match-grade barrel built for superior consistency and durability. It seamlessly integrates with the AFTERBURNER, a threadless, pin-fit micro compensator that vents gases upward to dramatically reduce muzzle rise and felt recoil without adding excessive bulk or needing a threaded barrel.
Together, this combo delivers up to 44% recoil reduction, allowing for quicker target reacquisition, tighter split times, and a smoother shooting experience, all while remaining holster compatible with most open-ended designs.
Whether you’re optimizing your EDC or refining your competition rig, the Radian AFTERBURNER + RAMJET combo offers true functional enhancement in a high-performance, minimalist form.
