I have never been a fan of ported barrels. I have owned and shot just about all brands and lengths of 44 Magnums and several big boomer Contenders 358 JDJ, 45-70, 444, etc. 2 years ago I got my first ported revolver S&W 460XVR. Love the gun - hate the muzzle blast. I made a plug to press into the port to eliminate it. It really did very little or nothing at all to affect the recoil. I like it better without the port.
As had been said by the others, ports are noisy and dirty. Hunting guides hate them due to the side blast.
