I want to build a gun specifically for the hardball event in Bullseye. The basis would have to be a GI-style 1911. Beyond that, I can use a custom barrel and have a trigger job. I see this as a learning project as much as anything else. Can you tell me what tools I'll need to accurize the gun? Will I need to go whole hog and have a milling machine? Or can I do it well without such lavish equipment? Do you know of any books that explain how to do this?
