The Radian® Afterburner™ + Ramjet™ combo delivers a revolutionary upgrade path for Glock 19 Gen 4 owners looking to cut recoil and improve accuracy while maintaining a compact, concealed carry profile. The system pairs a match-grade fluted barrel with an ultra-efficient micro compensator, achieving 44% recoil reduction with 115g ammunition. Installation is tool-free thanks to the INTRA-LOK® mounting system and threadless barrel design—no Loctite, shims, or set screws—and the combo is legal for sale in all 50 states.
Construction centers on 416R stainless steel for the barrel with hardened 17-4 stainless steel for the compensator, both finished in DLC (Diamond-Like Carbon) coating to reduce friction and resist corrosion. The micro-sized Afterburner compensator measures 0.47″ in diameter. The fluted barrel reduces weight, improves cooling efficiency, and incorporates a gas-sealing chamber to enhance performance. A loaded chamber indicator is built into the fluted barrel design.
The 4.42″ barrel features a 1:10 twist rate and is cut from 416R stainless steel. When installed, the combo extends the Glock 19 Gen 4 to G17 slide length for broader holster compatibility, while angled front faces on the Afterburner facilitate smooth holstering. The result is unprecedented recoil reduction and match-grade accuracy in a concealed carry package for the Gen 4 Glock G19.
