I bought a 6" Nickle 586. I really like it. I agree that the 586 is similar to a Python. I think the SA trigger on a Smith is the best out there. 586's I own can't compete with the Royal Blue of the Colt, but I think the functionality is similar.
The Smiths are much sturdier and it is apparent that the Smith built like a tank compared to the Python.
Each have their place and I love them. I really like the vented rib on the Colt pistol. An expensive, but cool look.
Any one know how many Nickle 586's were produced ? I haven't seen a lot of them over the years.
