RADIAN WEAPONS AFTERBURNER + RAMJET for Sig P365 3.1″

Description

The RADIAN WEAPONS AFTERBURNER + RAMJET is a compact compensator and ported match-grade barrel combo designed for SIG SAUER P365 and P365X pistols with a 3.1″ slide. The threadless barrel and INTRA-LOK mounting system allow for simple, repeatable installation and easy barrel removal for cleaning. Construction uses hardened 416R stainless for the Ramjet barrel and hardened stainless for the Afterburner compensator; both receive a Radianite coating to improve surface hardness and corrosion resistance. When installed the combo increases the overall slide length to a P365XL profile while retaining concealed-carry form factor.
