The lighter springs seem to work well and some (Not Me) will go as far as to remove the arm of one spring from it's top mounting underneath the grip handle and are happy with them.
(Some Will deem this to be a dangerous practice and I can see their point.
I think that the real cure is to go with the trigger job using the fine stones to polish up the point of where the sear releases which will get rid of the creep.
The creep seems to be the real enemy as it can be agonizing to try and hold that sight picture while picking up the .030-.040 of slack that can exist...I have gone as far as decocking the gun and trying again after spending seven or eight sec waiting for the trigger to break on those shots at a 3" steel that is 50yd to 60yd away. The weight of the trigger pull (for myself) has never been an issue with the Ruger revolvers.
The trigger jobs seem to be more expensive in this part of the country (midwest) and the cheapest from a shop that I was able to find was $85.00...The work from that shop was very good though and the Smith would take the time to go easy, disassembling more than once if nessary. The result can often lighted the overall pull but more importantly, will let that trigger break cleanly which will make your BH a joy to shoot.
