Failure to feed and split casings - Lone Wolf Arms AlphaWolf Glock 20 Threaded Pistol Barrel

From the very first attempt to chamber a round it has stove piped, failed to chambered and all around not functioned. I've tried a vast assortment of factory loads, changed recoil springs and no change in function. This is a extreme waste of money when it comes to function and use. I can't depend on this barrel and that defeats the purpose of the weapon.
