Well, after looking over some of the options available, I have decided to make one of my own. I am doing it cheaply, easily, and realistically. For this, you will need 3mm sintra, bondo, glue/epoxy, and a 1-inch long ½-inch cylinder or tube.
The instructions are simple.
1. Cut out two of each of the pieces.
2. Round the top edge of the grip inlays
3. Glue the body of the pistol together.
4. Put bondo into the bottom of the barrel area and then glue the barrel into it.
5. Bondo around the top of the barrel inside the body and between the forward posts.
6. Glue the two tabs together and place them over the end of the barrel (before the Bondo dries).
7. Sand the edged flat.
8. Round the pistol grip
9. Prime and paint as desired. I suggest you use a non-etching primer as it will aid in keeping the integrity of the overall body.
