I have the following:
1. Bianchi 16HL Heavier leather and has a double speed-loader pouch. This is fine under a Levis jacket or other medium weight garment, but would be bulky under just a shirt. I don't use it much, as my reasoning is; if I'm going somewhere that I think I need 3 loads for a snubbie, then why not just carry my Ed Brown or Kimber Commander sized .45's in a Lou Allesi should rig. Somebody mentioned this brand above, and I really recommend them for product design, quality of design and workmanship and great customer service.
2. My other snubbie shoulder rig is a Safariland A87, which is a very nice rig, and I carry a speed loader two in my pocket. Very nice quality and pretty light weight.
3. Probably my favorite holster for a 2" Model 10 is an Alfanso K2 upside-down leather shoulder rig. The gun hangs upside-down with the butt facing back, and thus the whole thing hangs very flat on the front side under your garment. They were/are a California company and I believe I saw an ad for their products in a gun magazine in the past couple of years. Very good design, and good quality in my experience. Your gun will come out pretty fast with one of these. Best of Luck in finding the right one for carry.
