I have a CW9. I tried on an ankle rig at a gun show last month and almost bought it. It was a nylon sheath with a thumb break and fit right over my wal mart boots on my left leg (right handed). I wish now I had bought it. I got a nylon shoulder rig instead and small clip on IWB nylon sheath. They are fun to wear around the house but I am not "feelin' it" to wear them out yet.
I will probably get one next chance I get, just to have that option. I ALWAYS wear black gus Bramha boots from WalMart with large enough slacks or pants to be able to wear an ankle holster.
I really liked going to the gun show and trying them on. The lady was really nice. This is my second post here. Everyone is nice and helpful!
I am glad I can put in my 2 cents worth.
