I'm using a Blackhawk Carbon holster for my 1911 and I find it great. More like a concealment rigid holster, but I absolutely like the automatic active locking feature, which holds the gun pretty well, even with almost no passive retaining tension applied. And it does look like a holster, not like a plastic piece on which your gun rests and might fall from if you move a bit too much.
My only rant is, beign a 'concealment' holster, it is high, very high on the belt, good thing it can be tilted forward or backward.
