The Radian Weapons AFTERBURNER + RAMJET (brand part no. R0841) pairs Radian’s RAMJET fluted 9mm barrel with its AFTERBURNER micro compensator for the SIG P365XL, finished in a distinctive bronze, sold as a single drop-in combo that replaces the factory barrel and adds a compensator in one unit. The RAMJET barrel measures 3.7 inches and is built to match-grade tolerances, with a gas-sealing chamber for consistent pressure shot to shot. A loaded chamber indicator lets a shooter visually confirm a round is chambered without racking the slide. Radian’s AFTERBURNER compensator locks onto the barrel using the company’s INTRA-LOK mounting system, a taper-lock design where a tapered locking pin interfaces with an angled V-groove on the underside of the barrel to time and secure the compensator precisely. Angled front faces on the compensator help it ride smoothly into a holster instead of catching on the mouth. This bronze-finished combo is built for P365XL owners who want tamed muzzle rise and a distinctive look on their carry pistol.
