I had a few points expiring over at SpecOps last week, so I took a chance on the long (8 inch) Combat Master sheath for my 711. I figured that if it didn't work out, I'd find some use for it.
Turns out that it's a near perfect fit for the 711, right out of the box. I don't even think I'm going to bother molding the insert. As is, the shape of the choil gives just a nice little bit of retention in the liner, without interfering with the draw.
I just wanted to report in case anyone else was looking for an off-the-shelf sheath for their 711.
