I've been toying with a shoulder rig for years for either my G30 or G33, so I finally ordered a Under Armor rig from High Noon. I've got other HN products and have been happy with them. Received my rig for the G30 on Friday. Very easy to put together and adjust. Wore it all day Saturday underneath a lightweight and somewhat loose-fitting pullover top. After awhile I almost didn't notice I was wearing it. The Under Armor is very comfortable to wear, and from what I could tell didn't print at all. Not that I care much if it prints, but the G30 holster and magazine pouch fit so well under my arms I was surprised how "invisible" it really was under my top. Paid $95 (incl shipping). Not that I'm any authority, but for those looking for a shoulder rig, the High Noon product line may be worth considering, and they also aren't the most $$$ models out there.
