Galco Tuck N Go holsters?

[Olympus]

Has anyone tried the Galco Tuck N Go holsters? They're a tuckable IWB holster and I saw an advertisement in this month's G&A mag with a very affordable price. It looks like the holster is a soft suede-type material with a single "J" hook. I would like to get a tuckable iwb holster for times when I have to dress up. I have a nice little Don Hume iwb that isn't tuckable that usually wear. I just wanted to know how people like this Tuck N Go, since it wouldn't be my primary carry holster. The suede-looking material leads me to believe it would be fairly pliable and soft, so I like that aspect. The picture in the ad looks like it has a Springer EMP in it. I wonder how the single hook would do with an officer frame 1911. Probably same general dimensions as the EMP, but I'd say it would have a little more weight and didn't know if the single hook would be able to hold a .45.
