I make all my own holsters and they are all wet formed. I wet the leather and then put it in a food saver and vacuum it down to fit the gun.
You dont have to do that. If you dampen the leather and then put the gun in it, the wet leather will 'RELAX' to the form of the gun and not leave an outline on the outside. UNDERSTAND THIS--If you use a wet form method, you need to make a thin wooden or plastic filler that you tape on top of the barrel to fill in the space between the top of the front sight and the top of the frame. Otherwise, when the leather dries, it will pull down in that area and clamp your front sight, wearing it bad every time you go in and out. Study the custom holsters,,,notice the words "sight track". Thatis a plastic insert in the leather to keep the front of the holster straight so that the front sight does not bind.
Use too much neatsfoot oil and you will end up with a LEATHER SACK. It will make the leather soft and sloppy. After you have damp formed your holster you can use Lexol or saddle soap to maintain it. Using oil or greasy manure on your leather attracts dirt..I did not notice where you are from, but if you are in an area of fine sand, it willattract sand and turn the leather into sand paper. I like the inside of my holster dry. My pistols get enough wear as it is without sanding them.
Hurry Cane,,,you're on the river bottom there and around a lot of sand. If it was me, I'd wet relax that puppy and then wear it in.
