Nice rig for a DIY! Care to share the construction details?
Thank you. It's 7-8 oz leather - I believe it's shoulder. What I do first is trace the gun onto paper and then trace the design of the holster around the gun. Cut out the paper, and then trace it onto the rough side of the leather. Cut two mirror images out for each side of the holster using shears. Then I mark where to glue, then I glue the leather together, usually leaving some space where the gun is going to go. Let the glue dry.
Then it's time to mold the leather - immerse the leather in warm water for a few seconds, take out of water, then insert gun. Make sure it's in straight and how you want it, then start poking and prodding until the leather molds nicely around. Using a bone folder helps - a Sharpie pen is fine, too. I usually leave the gun in until the leather is pretty stiff. It'll take at least 12 hrs to dry depending on the weather.
I then use a sander to smooth the edges and make sure everything is even.
Then it's time to stitch. I use an 'overstitch' tool to mark where the holes will be, then I drill the holes on a drill press - use about a 0.1" drill bit. Then I use the double hand stitch technique using wax coated thread.
Then for the belt holes, I drill two pilot holes for each belt hole approx. 1.25" apart from the center of each (for a 1.25" belt). Then I use a chisel and chop away the leather.
Then I burnish the edges with the bone folder and gum tragacanth. The key to this is to rub as fast as possible creating as much heat/friction as you can. It makes the edges really smooth.
Then it's time to dye the leather (if you want) and then put a protective 'tan-kote' layer on throughout the inside and outside.
Let dry and practice your draw.
Here are some other ones I've done.
