I have a PC 3" double Magnaported 629, and a 4" 29. The 629, a RB, has checkered Fishpaws which are almost a copy in French Walnut of Pachmayr Compac Pros, only slightly thicker. The 29, a SB, has Pachmayr Presentations, SN-S. For my hand, each gun has the best grips money can buy for that gun.
The 629 recoils noticeably less, surely because of the porting. The smaller better-fitting grip may also help.
Outdoors, I see no disadvantage to the porting. At least with ears on, the recoil is the event, not the noise.
I had no trouble carrying the 4", except that IWB and climbing Mt Washington, the gun got wet. I sweat a lot. That's why I bought the 629.
