The Glock 19 is an excellent mid-sized pistol used in a wide range of applications. It’s utilized for everything from concealed carry and self-defense to competition shooting and law enforcement. Though the Glock 19 is a fairly smooth shooting gun, you might want to consider using a Radian Afterburner like the Radian RAMJET Glock 19 Barrel + AFTERBURNER Micro-Compensator Combo to improve both its accuracy and its overall performance.


This Radian barrel and micro compensator combo is perfectly designed and paired to take the performance of your Glock 19 to the next level. It comes with the Radian RamJet barrel, which is made from 416R Stainless Steel and rifled for better accuracy. It’s also fluted to make it weigh less and to provide it with better heat dissipation.


The Radian Afterburner Micro Compensator that comes with the Radian barrel can significantly decrease recoil when you’re firing your handgun. It has large vents that point upwards to reduce muzzle rise, resulting in a smoother shooting experience for you and quicker target acquisition. In fact, in tests with standard 115g 9mm ammunition, it reduced recoil by up to 44%.

The Radian Afterburner is built to be very easy to install, and its angled profile aids in holstering as well. The barrel and compensator will increase the length of your Glock 19 to Glock 17 spec. Therefore, it will still fit easily in any Glock 17 holster or a Glock 19 holster with an open face.

**Certain municipalities or counties may restrict its use, and certain states may restrict usage under some circumstances. Before installation on your firearm, we recommend you review your state and local laws to determine whether your use is compliant in your jurisdiction.
