Hey denfoote,
I see that no one has responded to your question so I'll jump on in. I saw their holstering system on the internet a couple of months ago and was intrigued. I finally got to see and handle one at a gun show this past weekend. It truly is a universal holstering system that will work for almost any size pistol. It is basically a plastic frame with a barrel insert (I'm sure you've seen the pictures). It conceals VERY well for concealed carry and takes absolutely NO effort to draw from ... it is smooth and fast. My only problem with the system is that it absolutely requires you to remove the system before rehostering ... the rep himself admitted that it is virtually impossible to reholster a pistol without removing the device, reinserting the pistol, and then replacing both inside the waste.
I don't know if this answers your questions but if you have more, please post and I'll try to respond. Good luck!
