I shot the GP well, but decided to bring it up a notch because I also have a Python. A high benchmark. The GP was very good with the Williams Firefly (?) sights and a lighter DA pull. It still fired quality HP's reliably. The only time it had light strikes was on harder primed practice ammo, Fiocchi in my case.
The GP was not the best balanced revolver because of the relatively small grips and a 6" barrel with a full underlug. The MC has a 4" barrel with a reduced underlug and should not feel nose heavy. The factory MC grip looks like a great aftermarket option for the original GP.
The 586 I think is an exception among the newer Smiths for its classy look. The short underlug also helps. (I am more interested in shooting the 38s, only occasionally the 357s). The Ruger is kind of exclusive for now. A used 586 might be the best deal as n everyday shooter.
