Areoflyer09 - There is also the PPQ Q5 Match. Though it is factory ported, so that would probably have to be considered depending on what you want to do.
I won't lie, I just want the blue trigger.

Although the slide has lightening cuts galore, the barrel is not ported. But then again, the blue trigger makes all that OK!
