Chris,
What do you contribute the sound reduction to? Is there some sort of sound reduction design built into it or is it just the no ports on the barrel allowing all sound to go forward? The 9mm is not a quiet round, so I'm curious.

It's just the length of the barrel. 16" seems to extract the most efficiency out of the 9mm round, more than a 45 would. I see about 150-200fps more from the CX4 than my CZ P01 using the same ammo.
