Unfortunately, private "civilians" aren't allowed to own Glock model 18s in the United States (since they are post 1986, the BATFE refuses to accept the tax for them).
I should have clicked the video first I guess! without it, that shows how little I know about glocks!!!! any idea if that specific glock model is manufactured by them in quantity for various military forces around the world or is it just something built as a custom in small numbers?
