So there is a company, OldFaithful Holsters, that sells excellent CCW holsters. The sell three or four kits in varying stages of assembly. From fully assembled ($75) to build it yourself ($30). I decided to purchased the build it yourself, and am very pleased with the product. My holster is very comfortable and practically invisible if I wear a decently fitting bottom up short. They are available in both right and left hand.
The kit right out of the package, note the flat sheet of Kydex.
Make a cut out of your pistol (give an extra .5" around the gun), use heavy foam from like a sleeping mat. Put a beer cap under where the trigger guard will be (you need an indent to secure the pistol).
Heat the Kydex to 325F in a toaster oven.
Align the Kydex and place the pistol on the Kydex. Stand, sit, put some heavy object on the foam/board/foam//board sandwich.
Hold for five minutes, cut, trim, and attach.
Note how I cut the Kyrex in such a way that the safety is always on, how awesome is that?
