It does? Do you even have a photo of one?
Just as a general point of interest, there is a lot of information in the world that doesn't make it to the Internet. Given Glock's history of using Non-Disclosure Agreements for both employees and for T&E, it would be more logical to assume the pistol exists, has been vetted via testing, but that those involved are under NDA until it appears publicly.
It exists.
I can only assure you verbally that it exists. Take it for what you will.
