Glock 43 – Radian RAMJET + AFTERBURNER Barrel & Comp Combo – 9mm
PLEASE DOUBLE CHECK DETAILS, MODEL FITMENT, SKU/MPN, SLIDE COMPATIBILITY, HOLSTER FIT, AMMO FUNCTION, AND INSTALLATION REQUIREMENTS BEFORE PURCHASE.
Radian Weapons built this RAMJET + AFTERBURNER combo specifically for the Glock 43 9mm platform. It gives the slim little pistol a matched threadless barrel and micro compensator system designed to reduce recoil, control muzzle rise, and keep the setup cleaner than a traditional threaded barrel and comp.
Available finish options are organized under the product variants. Verified finish options in this batch are Black, Bronze, and Black / Gray. This is the Glock 43 lane. Not Glock 43X. Not Glock 48. Same slimline family, different little monster.
Variants / Options
- Black
- Bronze
- Black / Gray
Fitment
- Fits Glock 43 9mm pistols when using the correct Radian RAMJET + AFTERBURNER Glock 43 SKU.
- Caliber: 9mm.
- Uses Radian’s threadless barrel and compensator system.
- Designed around the matched RAMJET barrel and AFTERBURNER compensator setup.
- Installed system may extend the overall muzzle profile closer to Glock 48 holster length, but holster fit must still be verified.
Does NOT Fit / Verify First
- Does not fit Glock 43X unless your exact SKU specifically confirms otherwise.
- Does not fit Glock 48 unless your exact SKU specifically confirms otherwise.
- Does not fit Glock 42.
- Does not fit standard double-stack Glock models such as G17, G19, G19X, G26, G34, G45, or G47.
- Does not fit large-frame Glock models such as G20, G21, G29, G30, G40, or G41.
- Do not assume compatibility with aftermarket slides, altered slide noses, non-OEM slide dimensions, custom recoil systems, or non-standard lockup geometry without verifying clearance.
- Not a threaded barrel and not intended for suppressor mounting.
- Holster fit must be verified. The comp changes the muzzle profile, and holsters are not powered by hope.
What It Does
The RAMJET barrel and AFTERBURNER compensator work together to help reduce muzzle rise and improve control during faster strings of fire. Radian’s INTRA-LOK system uses the taper-lock principle, with a tapered locking pin interfacing with an angled V-groove on the underside of the barrel to time and secure the compensator without traditional muzzle threads.
Why It’s Worth It
The Glock 43 is small, light, and easy to carry — which also means it can get jumpy when pushed hard. This setup helps calm the front end without turning the pistol into a threaded-barrel plumbing project. The threadless design keeps service and cleaning cleaner, while the angled front faces on the AFTERBURNER help with holstering.

Tools Needed
Use the included hardware and follow Radian’s installation instructions. Basic bench tools may be needed depending on the exact package. Do not freestyle the install with the wrong tool like you are trying to lose a fistfight with a set screw.
Install Notes
Install correctly, verify the compensator is locked and timed properly, and function-test the pistol before trusting it for carry or serious use. Tiny pistols punish sloppy setups. Compensated pistols can also be more ammo- and spring-sensitive than stock setups, so test with the actual ammunition you plan to use.
Verify Before You Buy
Verify your exact pistol model, exact Radian SKU/MPN, slide compatibility, holster compatibility, and finish selection before ordering. If your supplier confirms Glock 43-only, do not list Glock 43X or Glock 48. The skinny little names matter here.
