Now grab a container large enough for the holster and put a couple drops of dish soap in it. I have read that the dish soap acts as a lubricant so the boning tools slide on the leather easier, it seems to help so I always use it.
Now fill the container with hot water, about as hot as you can stand to hold your hands in. Don't use boiling water, if it's to hot the leather will get brittle.
Submerge the leather in the hot water and count to 20, it doesn't need to be soaking wet.
Once the leather is wet use a paper towel to pad off any standing water and then stick the gun in it and start forming it with your fingers.
Make sure the gun is centered and not twisted. Also make sure there is plenty of room for your hand between the front strap of the gun and the holster.
and don't forget ... Always make sure the gun is empty!!!
