One thing to consider is that a .357 has to have the worst flash of any handgun caliber. That said, I have seen photographs of ported guns fired at night in articles trying to determine if porting is distracting or not. It seemed to me in the pictures that if there was a lot of flash from the ports, there was also a lot of flash from the muzzle! In the dark, they were both noticeable so you would get the same effect on your eyes, ports or no ports. I have several guns that are ported and some that are not. I'll take the porting and control anyday over the non-ported guns. 44 Man
