Porting is ONLY recommended if you intend on doing quite a bit of rapid fire shooting.The whole reason for porting is to get that muzzle down more quickly for the next round to be fired.Remember that there are several drawbacks to porting including,extreme muzzle flash in lowlight and (to a lesser extent) loss of pressure. Also porting in many cases can indeed cause accuracy problems due to burrs in the holes, pressure drops just prior to the barrels crown, etc.
