Not exactly. The D/A pull on a S&W revolver is partially a product of the mainspring. It is also partially a product of the rebound spring. A lighter rebound spring will improve the feel of the trigger pull at the expense of safety. The primary safety in a Smith revolver is the rebound to hammer fit and timing. With the rebound in the forward position, the hammer cannot strike the primer, ever.
To reliably set off a primer on a non-magnum cartridge, you need 3.5# of mainspring tension (3.75 # for a magnum). Some aftermarket springs will cause light indent misfires.
