I picked up a few of these from the guy who I took my CW class from. I got them for some guys I work with. They are really pretty nice and a great idea. They're made by a company named Roma leather. They make a bunch of leather products including some concealment items. The organizers are all I have and can get.
If anyone's interested pm me. They are selling for $45-$65 online that I've seen. I got them a little cheaper.

BTW....My Springfield XD40 4" fits easily.
