Cam's Review of Jacob Grey Firearms 9mm Complete Upper Assembly
to start off the thread pitch is not 1/2x28 its actually 1/2x36 and my order says it once purchased but the items description is wrong.
Meanwhile if you know anything about 9mm barrel the feed lip is slightly small which should cause error for basic fmj round but if you were looking to do HP or any other odd shaped tipped rounds then there is the potential for feeding errors. This isn't a bad upper by any means, it just means it wont be a reliable home defense if thats what you were thinking.
