The Glock 47 MOS is the newest 9mm pistol in Glocks lineup. Originally developed for Department of Homeland Security Customs and Border Protection, Glock has announced that it is now available for civilian use. The Glock 47 MOS pairs a Glock 45 frame with a Glock 17 slide. This modularity allows the shooter to also utilize Glock 19 magazines. Another point of interest is that the Glock 47 slide can be used on a Glock 19 frame to allow for the highly coveted "Glock 19L" configuration.
