Ordered for glock 19, kept getting a glock 17 barrel - Shadow Systems Glock 19 Gen 1-5 Match Barrel

This is a great looking barrel. Amazing color and love the fluting to lighten the barrel. However I've ordered this barrel twice now and it is not the length of a Glock 19 barrel. The first time I ordered, it was over half an inch passed where a standard Glock 19 barrel would be, but it fit perfectly in my Glock 17 so I decided to keep it. Ordered a 2nd one for my Glock 19 hoping the first one was a mistake and they put the wrong barrel in the right packaging. Got the 2nd barrel and received a barrel with the length for a Glock 17 and not a 19. Exchanged it for the Agency Arms barrel instead. Maybe this time it will be the right barrel length.
