20L/40 40 S&W by CGH, June 27, 2019
Excellent quality! Fits my Glock 40 mos perfectly. Tight lock up. The external flutes make it easy to tell which barrel is in the weapon. Good snug fully supported chamber. Shooting the 40 S &W out of the G40 platform is a blast!

This barrel does not fit the Glock G40 as advertised. When I called Wolf Barrels about it, I was told that this barrel is for a G-20. It is marked as fitting a g 2o and a g 40 however the shroud just ahead of the chamber is too long to allow the g 40...
