From a fellow holster maker, you are off to a good start. Wear it, use it, take it to the range. This will give you some good ideas on where to make changes on your next project. I suggest wetmolding a sight track. Its easy to do. I use a 1/4" dowel cut slightly longer than the length between the front of the rear sight and the rear of the front sight. Using a utility knife notch the forward end to nicely fit over the front sight. Tape it in place using blue painter's tape. Doesn't leave residue on the weapon. Now it is ready for wetmolding. Remember to add just a drop or two of dish soap to the water you are using to dip the holster to wet it. Good luck.
