No, Mojo you are correct. The PX4 Storm (and the 8000 before it) has a similar rotating lugged barrel. Pretty sure the 1912 Steyr is this way as well. From what little I understand of the article, the Glock 46 exists to be a viable candidate for German Police pistol trials/selection.
I'm curious to see how this one plays out in the long run
M1907 Roth Steyr 1907. Note that the way the striker works so far as being only partially cocked is very much like the other Glocks...it's almost like Glock is going back to the very first Austrian pistol with the return of the rotating barrel. I owned a cutaway M1907 - a very interesting early automatic pistol.
