Shadow Systems 9mm Full Size Threaded Fluted Bronze Barrel

Shadow Systems barrels feature minor improvements intended to create more consistent lockup without compromising reliability.  Our chambers are fully supported and can be fired with hot +P ammo and lead bullets.  We have sample barrels that have survived 5 proof rounds so it is unlikely you will have issues with any mainstream, commercially available ammunition.
