Any of you tried Custom Carry Conceptsí Adjustable Cant IWB Holster and/or Comp-Tacís C-TAC Holster (or even any of these companies)?

Jut by looking at the pictures, Comp-Tac's C-TAC Holster ...



looks like they use slightly thicker Kydex than Custom Carry Concepts' Adjustable Cant IWB Holster

.

Any thoughts?
