[TASF]Overkill has a ported model, ask him.
Since I have both of the ones you are considering, I would suggest the tactical. Should be just right for what you are going to do with it. The ported V-10 is nice but as TASF Overkill has already mentioned it does have some drawbacks. The V-10 has some unique features and it is visually interesting, but for a all around range model the Tac is the way to go.basically going to be a range gun, just for shooting day, and I'm somewhat of an accuracy hound
