IMHO - same thing...if not actually more difficult.Accuracy was excellent, but I'll confess to stacking the trigger. I wasn't shooting truly double-action like I do with my 586.
I look at stacking the same way I look at a set trigger on a rifle.
You take up the heavy work of moving the cylinder and retracting the hammer, then just "ease it on over the top" ever so gently when it hits that special spot that only your trigger finger knows - that drops the hammer.
