I have had Good Luck with the Delton Kits as well. Silencershop.com has Zevtech Theaded Match Grade SS 9mm Barrels for Glocks 34,17,19 Free Shipping ! I ordered one for My 34 @ $225 $ USD.
Yup would have preferred an A2 but this will do until one becomes available. Going with a standard buttstock, Ill use the collapsible tube and buffer on something else I am working on.
