I forgot all about the 18...and the mysterious Glock 7
I cant let you put the Glock 7 in the 9mm Glocks familly.
"That punk pulled a Glock 7 on me, you know what that is? It's a porcelain gun made in Germany. It doesn't show up on your airport metal detectors and probably costs more than what you make in a month."
You will notice that Glock make their Glock 7 in GERMANY and not in AUSTRIA like their other models.
Maybe its even too secret to be build with the other Glocks and the had to make a special factory in another country.
The Glock 7 is so mysterious that we dont even know if its a 9mm, maybe it has its own caliber just as mysterious as the gun itself.
We should contact Glock and ask them about it to know what caliber it is.
Maybe call a gun store and ask if they have the Glock 7 in Gen4 yet or if they only have the previous Gen3.
