Single action approximately 75% of the time and DA, 25%. Just like others have posted, it depends on which S&W revolver is in my hand or hands at the time.

My 6"+ models see a lot of SA time. The 4"- models see a good combination of both with an emphasis on DA, point at shoot from 3 to 10 yards.

Some but, not all of he shorter barrel models have had springs replace to aid with DA shooting and the modifications are more than worth the effort.

The longer barreled models are fantastic at breaking rocks, cans and other targets of opportunity at 25 yards and more but, in SA mode.
