You can wish list the item for notification but I would get on as many vendor notification lists as possible for the best chance of getting one soon. Davidson's Gallery of Guns will let you search many Vendor inventories simultaneously.

It was last priced at $1003.00. There is no way of knowing when it will be back in stock. Recommend you add it to you wish list, if you haven't already, and Bud's will notify you when it is available. You may want to consider becoming a Team Bud's member, if you aren't already, as that will make the 90-day layaway available to you for this pistol and give you a better chance at getting one when in stock. You can also use the new "Notify me when available" button which Bud's recently added.

Richard there is no way of knowing when it will be back in stock. I suggest that you click the notify me button and Buds will email you when the are available this in no way obligates you to purchase the gun. It just notifies you that they are available again

No one knows when an item will return to stock. Bud's places the order for an item and then waits for the manufacturer or distributor to deliver.
You can go to the item and click on "Wish List" and be notified immediately when it is in stock again.
