The Radian Weapons R0874 Ramjet + Afterburner Combo is a matched barrel and compensator system engineered to reduce recoil and improve accuracy in your Glock 19 Gen4. This is a complete upgrade package—not just an aftermarket barrel, but a precision pairing of a ported Ramjet barrel with a micro-compensator designed to work together via Radian's INTRA-LOK mounting system. If you carry a G19 but want the handling benefits of a longer sight radius and compensated recoil impulse without a full-frame gun, this combo delivers both in a package that fits standard G17 holsters.
The Ramjet barrel is machined from hardened 416R stainless steel and ported to shed gas and energy forward. The Afterburner compensator is milled from stainless steel, with angled front faces that aid in holstering. Both components receive a Radianite coating—a hard, low-friction finish that resists corrosion and erosion from muzzle blast. The real innovation here is the INTRA-LOK tapered locking system: a simple screw interfaces with an angled V-groove machined into the barrel's underside, ensuring repeatable timing and alignment every time. Installation and removal are straightforward—no special tools beyond the included TORX bit—and the threadless barrel design makes field cleaning quick and hassle-free.
Mating the Ramjet and Afterburner extends your G19's slide length to G17 proportions, which means you can use any Gen4 G17 holster in your collection. That's a genuine practical benefit if you already have holster investment or prefer the ergonomics of the longer platform. Radian recommends reviewing your state and local laws before installation; this combo is legal in all 50 states, though certain jurisdictions may impose restrictions on compensated firearms under specific circumstances.
