It’s just ugly, plus it’s fun to stir up the S&W 1911 fan boys.
My real dislike is the external extractor isn’t a JMB-original design in either the BHP or the 1911 pattern pistol. Don’t hate the hater. It is also a portal for the introduction of dirt to the unnecessary addition of moving parts. In the function of spent casing extraction, less is more and the genius of Mr. Browning is evident in his simple, one-piece extractor design.
Now to your statement, "...they require no retensioning/tuning of the extractor." (sic) In my life long experience of shooting the original "true" JMB 1911 pattern pistol I have yet found the need to retention the extractor. I have found the tuning of the extractor to be a brilliant exercise in allowing you to drop your brass exactly where you want! Do that with your spring and moment arm.
Still, going back to what the OP asks, the S&W scandium alloy frame is a gem. Very light weight, but HIGH strength (I have read that you are an engineer; perhaps you can explain to the rest of us blue collar types, how this alloy works so?). Too bad the OP has already made his purchase, especially with Smith coming out with their new Enhanced Series. It will be my first purchase of a 1911 w/a barrel less than 5", but with a rounded butt, light but extremely strong frame, and so many other premium features, I will not only carry it all day, but intend to fire it so often that even if I have to dip into my beer money, I will spend as much on ammo as I do my rent - no kidding! No worries!
My statement about "adjusting" the internal extractor is not from personal experience, but from reading over many years in gun mags about the sometimes requirement - right or wrong. STOP! I know, just because some hack has written a published article, does not mean that he/she is some guru on the subject, but having just spent several bucks on the mag, I have to read it.
