Firing Squad polished, Blue PVD coated Glock 19 gen 1-5 threaded barrel.
*As all Glock barrels do, the slide will hit the top of the barrel and will remove some of the Blue PVD coating. This is the only place where coating is removed. There is no way around this. Once installed and racked in your Glock, all exchanges are void*
For a harder coating, please choose TiN (gold), DLC (black), TiCN (copper), or go with stainless.
