BTW: The Glock 18 and 18C do not have a burst mechanism.
The Russians have a couple of new machinepistols which have replaced the old APS Steckhin (9x18mm PM) in some units. This page
from the Russian Ministry of Interior (MVD) shows the Drotik (5.45x18mm) and the Pernach (9x18mm PM and PMM). The 9x18mm PMM is essentially a 9x18mm Makarov +P+ loading.
