First of all, Mag-Na-Port does fine work and is a most highly reputable company.
Porting doesn't actually reduce recoil, but muzzle climb, or flip. And, in a relatively moderate recoiling handgun, really isn't necessary. I've found where it comes in handy is with the big .454, .475, and 50 calibers.
And, for a small gun used at close quarters, the possibility of being burned by the ported blast has turned me off.
