Dimensions

I've got more money sitting in holster bags than I'll ever recoup. I've dabbled in holster building before but I usually buy pre-made shells and go from there. This time I started with a flat sheet of kydex, and another of leather. And a piece of goatskin that I've used to line several shells in the past. It holds up very well using Aleene's Leather & Suede Glue to stick it to the shell.
This is the first time I've ever tried to form a piece of kydex for a pistol. Previously the only forming I had done was for a Benchmade folder.
I built a kydex press sometime back and had everything on hand that I needed to do this, the only thing I've lacked is the gumption and the experience. Oh, and the skill. But I gave it a try today and this is what I came up with.
I used my wife's oven since the Goodwill toaster oven I had bought for working kydex wasn't big enough for the sheet I started with today. I still need to apply some heat in a couple of places, and I'd like to insert a tensioning adjustment. And put some coloring to the raw edge. I burnished the edges using my drill motor and a wood thread spool with a piece of all-thread thru it. I made a couple of those in different sizes and they work pretty well. Still can't make a professional edge because I've never found a quality hand skyver (ie not made in China). After those touchups andonce the straps stretch out a bit it'll be about done. My personal preference is for holsters to clip or snap to my belt, and the flatter the back the better.
I don't know for sure that I won't buy an STX from Garrett eventually, but for now this will be something I can play with.

I swapped the screws and washers. Still need a couple of finishing touches but it works for both my P227 and 229 SAS'. I'll wear it today while out and about to find out how comfortable it is.
