A few days ago, I got a D. Hume 721 OT for my G30. I've carried it for a couple of days now (in lieu of my 23 in a CBST), and have found it quite satisfactory. While it is a belt holster, it rides fairly high and tight and conceals rather well under an untucked casual shirt. Riding on the belt, it was comfortable and supported the G30 just fine. I consider it a plus that I can wear it much closer to the 3:00 position than I can the CBST (inside the belt presses the weapon, uncomfortably, on my bony hips). The new Hume 721 was very tight on the weapon and needs some break-in; out of the box it was difficult to pull the 30 out of the holster when riding on my belt. Of course, I would rather have it too tight and have to break it in, than too loose and worry about weapon security. For me, the big drawback is that rather than slipping clips over my belt, I have to feed the belt through the holster when I put it on or take it off. Bottom line, for comfortably carrying the relatively thick G30 I thought the Hume 721 did a good job and, at about $40+ new, it's fairly economical.
