My $0.02, get a Wolf spring pack for less than $20 and see what happens. It won't be as good as a professional action job but it will get you pretty close. Shooting about 1K rounds down the pipe will help also.

I recently installed the reduced recoil pack in a Model 17. I had been reluctant to do so because of ignition reliability. It now has a near perfect trigger and only 2 FTF out of a box of 333 rounds (which is probably better than before the swap).
