Okay guys... here is an extract from the Luger blueprints addressing the issues you have brought up... I have created it in white on black to be a little easier to read... I hope this answers your barrel questions...

The CD of Luger blueprints will be available "real soon now" as they say in the software development business... :D

Thanks John for the print info. I have the "Uzi" blank threaded,chambered, and installed to the barrel receiver. As I don't have the extractor grove cut yet,I removed the extractor from the breach block prior to assembly. Which brings up the question,could the headspace be checked through the now open(no extractor), gap at the top of the breach block?

Hey! Johns blueprint has the stepped chamber dimensions I've been curios about. Thanks John.
