What Scota says. If you don't have alcohol water will do, it just takes longer to dry. Be sure the plastic wrap has the gun sealed well, they can rust very fast. You really want the holster stiff rather than soft and floppy. I just did a cowboy holster for a cartridge Remington for my brother a couple of days ago. The holster came almost flat, you could barely get the gun in. After molding it the revolver drops in, stops in the same place every time and is held firmly. While the holster is drying you can mold it to the contours of the gun for a really good fit and neat appearance. Gently squeeze and press the damp leather against the gun going back and doing it several times while it dries. Be careful not to overdo it as it can leave obvious finger or thumb marks in the leather.
