Background info so you better understand where my mind is at:
I'm an electrical engineer working in the automotive industry specializing in automation. Specifically with powertrain OEM's that make machines/machining centers using CNC's and the latest state of the art servo motion/drive systems.

S&W 27-9 and 29-10 perceived assumptions according to forums and observations:
From reading everything possible I could find on both the model 27 and 29, every forum thread and conversations decrees the original "classic" 27-2 or 29-(1-5) to be superior to the new issue classic line aka 27-9 and 29-10.

To this point 99.9% are suggesting the older models are better based purely on aesthetics and nostalgic feelings of the good old days. "When I was a kid we had vacuum tubes and my radio was bigger and sounded better than my new 4K Ultra HD TV we just got black Friday"....I digress...point is older isn't better...PERIOD! This fact is specifically and especially true with regards to electronics and manufacturing in the 21st century.

Everyone can agree that older is often perceived to be of higher value and if there is a market for that older product then people will drive that perception. However, older isn't better in any other paradigm other than collect ability and nostalgic/monetary value. I mention this not to cause a debate but to clarify the new v old argument as it pertains to the new classic line of S&W revolvers and the "classics".

Why newer is better and my point:
I am working with a company that make machines (essentially 3D printers) that produce an aircraft grade aluminum part for the new Boeing Dreamliner that shoots a laser into a pile of aluminum dust and creates completely finished product (totally dumbed that down but it's awesome!).

My point is technology improves manufacturing and specifically improves the quality by eliminating human error. Robots, precision motors/controls and advances in metallurgy have advanced just as fast as the computer. To suggest that an older model handgun would be of better quality than a newer model handgun using state of the art CNC machining and tools would be a straight lie used to perpetuate the above myth/perception. Having a 100 highly skilled craftsmen make one handgun back in the day is not even close to the quality a robot can provide given the same task...by the way I'm using the term robot to me literally robot as well as automated machining center.

1. MIM parts vs machined - stupid argument other than aesthetics. Everything bad you think you read about MIM parts is a myth.
2. Lock vs no lock - again just aesthetics
3. Blued finish is darker than the original - Yes even the process to blue the finish of a handgun has improved exponentially

I could go on but I'd like to ask if someone could present me with a valid scientific reason to consider an older S&W 27 and or 29 over the brand new S&W Classic versions other than it nostalgia and collect ability? I buy guns to shoot and shoot often. I don't collect guns and I don't ever resell them so could someone please make a legitimate case against the newer classic line of S&W other than aesthetics?

Note: I'm pulling the trigger on a M29 for me and a M27 for the girlfriend for x-mass.

Thanks in advance but please don't provide links to the same old arguments from past threads. I get it everyone wants to make love to a 27-2 and burry a 29-3 in the backyard like a brick of gold.

Quick example (maybe apples and oranges but whatever): I collect Rolex watches and know everything there is to know about them, however, the older Rolex Submariner's are not better than the newer ones made today. Everything in the new watches from the steel that is used to make them to the machining process used to cut the parts of the precision movement cannot compare to the same exact watch manufactured just 7 years ago in terms of quality.

Thanks,
Chris
