The Glock 19 is an excellent mid-sized pistol used in a wide range of applications, from concealed carry and self-defense to competition shooting and law enforcement use. Though the Glock 19 is a fairly smooth shooting pistol, if you want to improve its accuracy and performance, you should check out the Radian RAMJET Glock 19 Barrel + AFTERBURNER Micro-Compensator Combo.

Better Accuracy

This barrel and micro compensator combo is perfectly designed and paired to take the performance of your Glock 19 to the next level. This combo includes the Radian RamJet barrel, which is made from 416R Stainless Steel. This match-grade barrel is rifled for better accuracy and is fluted for lower weight and better heat dissipation.

Faster Follow-Up Shoots

The Radian Afterburner Micro Compensator that comes with this barrel can significantly decrease recoil. It has large upwards vents that reduce muzzle rise, resulting in a smooth shooting experience and quicker target acquisition. In fact, in tests with standard 115g 9mm ammunition, it resulted in up to 44% recoil reduction. The Afterburner is designed to be very easy to install, and its angled profile aids in holstering as well.

The compensator and barrel are designed to increase the length of your Glock 19 to Glock 17 specs. Therefore, it will still fit easily in any Glock 17 holster or a G19 holster with an open face.

    I had high hopes for this thing and it exceeded my expectations. They say it reduces muzzle rise and felt recoil by 44%, I’d say at least that much or more. You won’t be disappointed
