I've done this more than a couple of times and found that wetting the leather, covering the gun in Glad wrap, inserting the gun and sitting down to watch tv and kneading the holster/gun while I watch the tube makes for a great holster/gun match. I agree that forced heat drying is a No-No, air-conditioned air or a de-humidifyer is ok. I dis-agree that after the holster is formed and well dried that using conditioning oils will over relax the leather. I use Ballistol and my leather has never lost it's shape or body.
