Something to consider..today at the S&W Performance Center there a few models coming out with sleeved barrels,sidelock cylinders,full lug barrels,short stroke actions.etc.. These were all features of the 70's era Dan Wessons.
As it turns out, an Italian company is going to turn out Reproduction Pythons:

First gun I bought was a Hi Standard Sentinel MKII .357 4" in the early 70's, a friend said I needed a gun for home defense. I put maybe 50 rounds through it in the late 70's then stored it for around 30+ years while the military sent me here and there. Sold it 4 years ago and just recently became interested in firearms and bought it back last week.
I took it to the range today and put 100 rounds through it and it was extremely accurate...
