Brownells 75th Anniversary - A Shooting Heritage

The Brownells Extended Barrel for Glock® 19 is designed to work hand-in-glove with our extended slides for the popular compact 9mm pistol. Due to changes in the slide-to-frame geometry caused by mating the long slide on the compact Glock 19 frame, a factory Glock 17 slide will not work with our slide. This extended barrel is correctly configured to ensure that your new "long slide" G19 functions perfectly.

This extended barrel and the slide work together to give you a longer sight radius for more accurate shooting and better recoil control - and a pistol that’s more comfortable to shoot all around.

Our Extended Barrel for Glock 19® is available with a Plain muzzle or Threaded (1/2"-28 tpi) to accept a compensator or silencer.

  • Easy drop-in installation
  • 9mm Luger chambered (of course!)
  • Corrosion-resistant 416R stainless steel
  • Durable black Nitride finish for excellent resistance to surface wear
  • 1-10" right-hand 6-groove rifling
  • Threaded model has ½"-28 muzzle threads

Constructed of high-grade 416R stainless steel alloy, this extended barrel is precision machined to ensure an exact fit to drop right into your pistol’s extended slide and preserve the superior reliability and performance your expect from your Glock® 19.
