Actually, the real comp would be considerably more expensive than the average price of porting done in the existing barrel and slide. Price depends totally on the comp price and labor of the smith who does it. It would work far superior to the holes milled in the existing barrel, if thats what you mean by hybrid barrel. Schueman makes a hybrid barrel with big holes in the top and the slide milled away. Its THAT what you mean by "hybrid"?
Depending on method of carry, I don't think that barrel length is an issue. It is the grip and top rear end of the slide that prints in most carry methods.
