I've got a Taurus 7-shot .357 that's ported. I bought it many years ago on a whim while up in Nashville on a day trip. It shoots well and I suppose the porting holds down muzzle rise a bit but since I don't have another 4in .357 of the same frame size I really don't know. As far as felt recoil I think the mushy grip (whatever Taurus call it) probably does more than the ports... but then maybe the mushy grip allow the gun to move more in my hands thus allow more muzzle rise... whatever. Waste of hole drilling as far as I'm concerned, but if you're going to drill a bunch of useless holes in a .357 revolver seems like Taurus would be the way to go. Looks kinda neat though.
