Anyone used a Mernickle SH6 shoulder rig?

[Tallinar]

Has anyone here used a Mernickle SH6 shoulder rig? I've been searching for awhile now for a concealable shoulder rig suitable for a 4 5/8" New Vaquero (carried either vertically or with a slight forward angle), and this caught my eye as a real possibility. I'm having trouble locating any reviews or pictures of folks wearing one. Can anyone here comment?

Link to Mernickle's page for this found HERE.

Thanks.
