re: " shooting mostly DA : do you shoot with a very slow pull of the trigger in order to have maximum accuracy ? Or a
fast pull for speed ? "
My 627 & 327 use in speed steel relies for best scores, on DA mostly. Sometimes I'll need to use SA on the first distant target of a stage, then revert to DA. The 'cylinder indexing trick' or 'stacking' is slower than the SA-like release once you find the target. After a bit of training it gets more comfortable. I shot SA cowboy style for a couple decades before changing to speed steel event. It was just a little training exercise, and my score improved rapidly.
