Glock’s newest pistol is the subcompact .45 ACP chambered Glock 30S.
The Glock 30S has a double stack magazine, like the Glock 30, and a slim slide, like the Glock 36. You could almost call this gun a FrankenGlock. The existence of this pistol has long been rumored since Glock aficionados first reported that the slimmer Glock 36 slide could be made to work on the double stack Glock 30 frame.
We will have more information when Glock officially announces the new pistol.
