DA vs. SA Revolver Advice Needed

[TMan]

Having never shot a DA revolver, I was thinking of getting one or another SA revolver. I find the loading of the SA a little cumbersome so was thinking a DA might be easier. I assume unless it was advertised as DAO you can shoot a DA in SA mode. My concern is the trigger pull. Do the DA revolvers require more pressure? After 200 rounds through the little Bearcat today, my index finger is a little tender.

["DoubleAction"]

TMan; The double action revolver possesses a longer trigger travel in order to rotate the cylinder and cock the hammer, with one single stroke. During the stroke of the trigger the locking lug will also engage the cylinder before the hammer is in it's full travel rearward. On the S&W revolvers, this will be a sign to set for the shot like a two stage trigger. For the Python, the hammer has a V-Spring, rather than a coiled spring, with a longer hammer fall. This means a longer trigger travel than the S&W, with the V-Spring performing very different than the coiled spring. The V Spring can be tuned to act with a single stage stroke, but the stock trigger will get slighlty heavier as the hammer reaches near the end of it's rearward travel before falling; This is a two stage trigger. I've tested some factory Pythons with 8 lb take ups, with a 9 lb. throw. The S&W revolvers require action jobs for such, but the trigger's pull weight is short and consistant when done. The trigger travel seems to be one thing that keeps the finger working,because of the work involved with rotating the cylinder, and cocking the hammer. On heavier triggers, it requires more energy; If you get a heavy handed double action revolver, you will know it right away.
One way I sometimes warm up for any double action revolver is to start off shooting a S&W 29, using 44 magnum, very slow. Afterwards, the .357 magnums are so light in the hand, it seems almost like shooting 38 specials.
Although the Single Action method of shooting the D.A, Revolvers is possible, I do not make a habit from it, and seldom do so.
Many Double Action revolvers was once designed as Combat Target Revolvers,designed for use in Military and Police applications; These are some of the prime specimens among double action revolvers.
