Hi Shaun. What is your price range? There are many great gunsmiths out there who would be happy to build you a great open gun. Many of them are in the dealer tent here on the forum.
Have you given any thought to 9mm? You'll find at a lot of matches you'll be busy resetting steel, taping targets etc and will need to leave a lot of your brass lay. That's painful with .38SC brass, not so much with 9mm.
