A lot of folks ask me if I could only pick one, which would I choose, the CZ-USA Scorpion EVO or the Sig Sauer MPX 9mm pistol? The CZ Scorpion is a mostly polymer 9mm pistol version of a Czech made SMG and the Sig MPX is a new US made pistol version of their new SMG. I talk through what I like and dislike about both and let you know which one I would choose if I could only have one.
