Radian Weapons Ramjet & Afterburner Glock 19 Gen4 9mm 4.42" Barrel Combo - Black

The Radian Weapons Ramjet & Afterburner is a replacement barrel and micro compensator system designed for the Glock 19 Gen4 or a compatible Gen4 9mm pistol. Chambered in 9mm Luger, the combo retains a concealed-carry-sized configuration while providing a compensated barrel assembly.

The 4.42" RAMJET barrel is machined from hardened 416R stainless steel with match-grade, fluted construction. It incorporates a gas-sealing chamber and loaded-chamber indicator. The matching AFTERBURNER micro compensator is made from hardened 17-4 stainless steel and adds 0.47" to the assembly. Its angled front faces are designed to ease holstering.

Radian's threadless INTRA-LOK taper-lock system uses a tapered locking screw that engages an angled V-groove beneath the barrel. This arrangement times and secures the compensator without Loctite, shims, or setscrews. Radian states recoil reduction of up to 44% when the system is used with 115 gr ammunition.

Both stainless-steel components wear a black DLC finish selected for low friction, hardness, and corrosion resistance. Once installed, the Glock 19 slide assembly reaches approximately Glock 17 overall length, allowing use with Glock 17 holsters. This configuration is identified specifically for the Glock 19 Gen4, not Gen3, Gen5, G19X, or G45 configurations.

This new component combo includes:

• One RAMJET match-grade fluted pistol barrel
• One AFTERBURNER micro compensator

This is a barrel-and-compensator component kit, not a complete firearm.
