Cody - short answer - never. It is out of production.

Cody, I don't think you will see this "Shadow FDE" model again. Glock ran this Gen 4 batch and they are off to Gen 5, 43X, 48 etc. Possibly Secondary market or vendor that still may have them in inventory. BUDs had a very limited inventory of this firearm and they are gone now.

While I am sure that buds has them on order there is no way of knowing when it will be back in stock. I suggest that you use the notify me button. Buds will email you when they are back in stock This in no way obligates you to purchase the item. We are not buds employees we are volunteers that answer questions

Cody, you should keep it "Wish Listed" / "Notify When Available" list for notification as this particular Pistol is out of stock and was very popular so it may be quite a while as it is almost impossible to say when. It is also out of stock at other vendors here as well : https://gun.deals/search/apachesolr_search/151550008173
