I like them very much for OC & CC. I really like the way the holster is constructed with all of the molding done in the outside piece of leather. They are absolutely comfortable all day long. They do have a significant forward rake and carry best at 4 o'clock, so being aware of this when you OC is important. If you carry too far forward it can be difficult to draw from and too far back leaves your gun vulnerable to a grab from the back.
They have good retention for an open top holster, partially due to the forward rake, but the Level II folks won't find them satisfactory. To each his own. I like them a lot.
BTW, Mitch Rosen has a President model that is virtually identical.
