Radian Weapons R0873 Ramjet + Afterburner Combo Fits Glock 19 Gen3 Black/Gray Stainless Steel

The Radian Weapons Ramjet + Afterburner combo is a matched barrel and compensator system built to reduce felt recoil and enhance accuracy on your Glock 19 Gen3. This is a complete solution for shooters who want a factory-quality upgrade without the guesswork: you get a match-grade ported barrel, micro-compensator, and all hardware needed for installation. The combo is threadless and designed for straightforward takedown—drop the barrel for cleaning whenever you need to, with no tools except the included TORX bit for the mounting screw.

What makes this kit practical for carry is its engineering. The Ramjet barrel is machined from hardened 416 stainless steel and coated with Radianite—a finish that trades heat and friction for durability and corrosion resistance. The Afterburner compensator, also stainless steel with the same Radianite treatment, uses Radian's INTRA-LOK system: a tapered locking screw seats into a V-groove under the barrel, aligning and locking the compensator repeatably every time. The compensator's angled front face is designed to clear a holster during the draw. One important note: installing this combo increases the overall slide length to Glock 17 dimensions, so you'll need G17-spec holsters for carry compatibility.

Radian Weapons says this kit is legal for sale in all 50 states, but local laws vary—some municipalities restrict compensators in certain contexts. Before you install, check your state and local regulations to confirm compliance in your area.
