I see some mine is better, No mine is better concerning internal vs External extractors. I have a E series S&W 1911 with an external and it works beautifully. How better than 100% can a internal be? I realize the original was an internal but the one in my gun is a performance center piece and is about twice the width of a standard issue so it is not a light weight piece. As I said, how much better than 100% can you get? Thanks in advance, Frank.
