Do you have pictures, how close is your stitch line to the fire arm, what type of leather are you using - shoulder, belly, back? I use primarily shoulder or back, use the formula of one half the thickness of th gun plus one thickness of the leather to find my stitch line. I put my mold or gun in the holster when it is good and wet Should be pretty snug feeling putting the gun into the holster then using finger pressure start rubbing the outline of the gun until you can start to see some defenition then use boning tool ot other objects to refine the detail. Some people use heat to ste and harden the holster such as a small oven at 125 degrees or a drying box with a hair dryer blowing air into the box. I usually just set mine in the warmest place in the house to dry.
