The 27 isn't a "performance" model -- it's the full-size "N" frame (actually, the original platform for the .357 Magnum). What you're gaining is more strength -- and size and weight, which may or may not suit Amy.
Lugs and shrouds. Originally, the ejector rods on revolvers were bare under the barrel. Colts, which didn't engage anything, just hung out in the breeze; S&Ws engaged a catch under the barrel.* At some point in time, manufacturers enclosed the ejector rod (I guess to keep it from getting bent, which would disable ejection). Later -- and I think the Python was the first, but I could be wrong -- the shroud was extended the full length of the barrel. This added weight, making the revolver easier to control in firing for faster follow-up, and also making it steadier for deliberate firing (at least, if you've developed the required muscles). Many think the full lug also added visual appeal.
*If you go back 50-75 years and look at the S&W and Colt adds, there was a PR battle over the manner of lockup and the direction of rotation. I don't know if there's anyone out there who still gets passionate over the difference.
