Depending on if I am shooting Black powder or not, I shoot a Pedersoli Lightning, or a Win 73.
I used to shoot the lightning with black, but dont want to take it apart more than necessary anymore. I now shoot black in the 73 only, as its easier to clean up afterward.
Both of them have straight grips, as they just feel better to me.
The lightning feels better with a longer barrel as it doesnt bounce the sight picture around near as much as with a short barrel. I think its a 26". Maybe 24". Cant remember now.
My 73 also has a long barrel on it, but my wife has a 18" barrel on hers, and it feels fine.
Both of them are in 45 Colt, but work fine with my Schofield loads too.
A heavier bullet seems to make my Lightning run a little smoother.
