I've always loved inferno and I think that Valve did a bang up job bringing it up to Source. I agree that port is a bit frustrating since there is no where to avoid fire, but that just adds to the strategy. I find the machine gun and glock as a very good combo for that map, I can send out some cover fire for teamates plus I gain an edge when other players run out of bullets and reload. The glock or five seven would both seem to work well as pistols since they can fire off a lot of rounds fast and accurately.
