The holster is homemade from leather purchased at goodwill. You buy a nice purse at goodwill, taking care not to buy a brand name purse because they are more expensive. A non-brand name handbag or purse that you can cut up to make a fancy holster costs $2. Tandy Leather also has a nice scrap bin if you're at their retail store location.
The grips are going to be 3d printed with $2 in plastic. I have a 3d printer.
