Mag-na-porting works, but remember, it works against you when firing from retention and does your hearing no favors! My large belt gun is mag-na-ported. It is a 5" 629-1 and I shoot a 165 gr. JHP handload that packs 1000 fpe. The full underlug barrel, porting and regular practice are what allow me to handle all that power. Firing from retention involves tilting the gun away from my face to about a sixty degree angle and aiming down for a pelvic shot. That's the way to avoid a face full of burning powder. I also wear eyeglasses.
