Shield Arms has recently expanded support for the popular Glock 43 slim line pistol with the introduction of the Z9 9+1 magazine. Shield Arms states “Introducing the Z9 pistol magazine for the Glock 43- a 9 round steel magazine the same length as an OEM6 round magazine with pinky extension, but with 50% more capacity. With the Z9 magazine, your Glock 43 becomes a 9+1 capacity gun in a much smaller and more concealable package that a Glock 43x (thinner,shorter in height, lighter), but with 50% more capacity than an OEM Glock 43″
