Yes your 03 can be converted into a halfblock, but listen to my words. SEND IT OUT OR ORDER A BODY. From the sounds of it you don't completely understand the operation of a halfblock, and you NEVER start a project like this without a full understanding... cuase then you'll mess it up... and things will just get uglier from there.
Please don't take it the wrong way, Im sure you know alot about your gun. But a profesional is called a profesional becuase they know what they're doing. You won't regret it.
