Open Gun Barrel - Ports - Compensator

[Triple]

Friends: I do not handle myself well with the English, I can read it, but nothing to write, if there is some can do it I am going away it to agraqdecer. Desire to know as is the best configuration for greater caliber in 9x19 and 38 sa. The question makes specific is, Hibryd barrel? , whichever holes? , that type of compensator, length of the sewer and the compensator, for both calibers. I consult them because I am arming a Paraordnance and I would like to know that it is the better standard or for IPSC Open I see that there are several versions, but generally always a standard version stands out. thanks

9x19: Length of barrel - hibryd 3 or 4 holes, compensator 3 or 4 ports o +

38 sa: Length of barrel - hibryd 3 or 4 holes, compensator 3 or 4 ports or +.

Thank you very much to help me, in spite of having to use an electronic translator
