Interesting approach that gets around ATF rules. It’s not the same as other similar approaches as it adds a 16" barrel as a bullpup. And, not just for Glocks. With some hot 9mm rnds, you could probably get close to rifle zip. In 10mm, from a 16" barrel, well, might be thumpy:
I would have thought so too, but according to this site, 9x19 typical handgun vs. carbine isn’t like the jump .357 Magnum gains between a typical revolver and a carbine.
How goes Col. MAC Like it?
That is the wonkiest thing I’ve seen in a long time.
