Don't know why one would limit their search for "Custom" Kydex? You can get true Custom work/fitting done from Ky-Tac @

http://www.cen-dex.com and MD Labs {aka "Mad Dog"} @
http://www.mdenterprise.com/holsters.htm Ky-Tac comes with screw tension adj. built in. The later two will build to suit your retention requirements for CCW, IDPA, etc. from very secure to speed for straight competition or in-between. All 3 makers hand mold & hand finish to a real "live" pistol not an aluminum slug, etc. You don't pay anymore than the mass produced, sometimes junk, sharp-edged "waffle-iron", unfinished or "cookie-cutter" Kydex that's often "Thick as a Brick" with poor retention and very marginal to unacceptable belt loop design, etc. If they don't get the retention just as you specify they will re-work the holster for you.
