Initial forming the sight track. This had to be tweaked multiple times throughout the process. Not having a pre-made form, I made do with the edge of a 1x2 piece of wood. Consequently the sight track is a bit wombly, but functional.
Pretty close to the final shape using a Dremel with a sanding drum to form the edges and smooth the contour some. There will be more finishing and touch ups before it is done. Next step is to affix leather struts to the Kydex body to which the belt clips will be attached.
I don't think I mentioned that this will be a tuckable IWB holster. Meaning you can tuck your shirt in and the only thing showing will be the belt clips and no need for a cover garment.
When boning or form fitting the Kydex to the gun, its easy to have too much retention even before adding any screws or rubber spacers for adjusting retention. I hope to finish the holster today and have it range ready for Friday.
