First off, forget the ported barrel. The blast coming up out of those holes is enough to blind or seriously injure you, and firing from inside a vehicle almost guarantees the gun will be close to you. I like the Taurus 3-inch 44 Spl, with fixed sights. Good shooter, easy on the hands/wrists, and no magnum blast and flash to contend with. I would absolutely avoid the Cowboy Ammo, you need a bullet with a wide meplat (big flat nose) or a good hollow point. W-W Silvertips and Speer Gold Dots are the only loads I've gotten to expand out of a short barrel, and I've tested a bunch.
On the other hand, I carry a 38 on duty (stupid local ordinances!) with Hydra-shoks in it, and don't feel undergunned. Of course, mine is a four incher, and I practice a LOT with it. My reflexes and visual acuity are a far cry from what they were in my 20's! :shock:
