Description
The Radian Afterburner and Ramjet for the Glock 43X is a matched barrel and micro compensator set, sold together, for the shortest of Glock’s Slimline 9mms. Radian designed the system so a carry gun can run a compensator without a threaded barrel. The Ramjet has no threads. Radian’s Intra-Lok mount uses a tapered locking screw in the Afterburner that seats into an angled V-groove under the barrel, which times the comp and holds it without thread locker. Install is a barrel swap: remove the factory barrel, drop in the Ramjet, reinstall the recoil spring assembly, slide the Afterburner over the muzzle, and torque the screw to 15 inch pounds per Radian’s instructions. No shims or crush washer. One screw frees the comp for cleaning.
Radian lists the barrel as a hardened 416R stainless steel Ramjet with flutes, a gas sealing chamber, and a loaded chamber indicator cut, and the Afterburner as hardened stainless steel. Both are finished black. Gas exits through one top port with no side ports. Radian says that on a 43X the combo extends the slide to Glock 48 length, so it fits open bottom G48 holsters. Radian’s stated design goal for the system was reliable cycling with the stock recoil spring. Included: Ramjet barrel, Afterburner, Intra-Lok tapered screw, and a Torx bit.
Fitment: Radian lists this version for the Glock 43X only. It will not fit a Glock 48 (longer barrel; Radian sells a separate G48 version) and will not fit a Glock 43, 26, or any double stack Glock. Radian states fitment for the factory 43X slide and publishes no list of approved aftermarket slides. The Afterburner only mounts to a Ramjet barrel.

Who it’s for
Glock 43X carriers, and PCSL 2-Gun or Tactical Games shooters running a slim gun, who want a compensator that comes off with one screw and who are fine moving to a G48 length holster.
Who should skip it
If you want to keep your current 43X holster, skip it; the slide grows to G48 length. If you own a G48, buy Radian’s G48 version. If you already run a threaded 43X barrel from the threaded barrels we carry for the Glock 43/43X/48, the Zaffiri Blowhole or Faxon EXOS-533 for the G43 family is the cheaper thread on option. Division rules: USPSA Production and Carry Optics do not allow a compensator, and IDPA SSP and CO do not either; IDPA CCP and ESP vary, so check the rulebook.
