Im no firearms expert but I do know quite a bit about Glocks or so I thought. The Glock 28 is a .380 that is not found much in North America.
Like the GLOCK 25, the GLOCK 28 in .380 is also blowback operated. Small in dimensions and weight, it is great in performance when carried concealed. Because of the low-recoil firing characteristic of the .380 cartridge, it can be easily and accurately controlled. The standard magazine capacity of this balanced pistol of 10 rounds can be increased to 19 rounds when using optional magazines.
The Glock 28 is the size of the Glock 26 from what I have been told and the Glock 25 is the size of a Glock 19
