I couldn't find any existing threads on this, which surprises me, as I figure lots of people are interested in doing so. I also don't want to bury it at the end of a (very long) discussion about my own S&W revolver, so I'm posting as a new thread.
Until recently, I assumed that if one wanted to reduce the trigger pull (staying within the range of what is safe and accepted), the part that would be replaced is the "rebound" coil spring that's found inside of the rebound slide. For a S&W 357 Highway Patrolman, this is an 18# spring. Since I was born without calibrated fingers to measure trigger pull, I ordered one of the small gages that measure the actual trigger pull. I should have that in a week or so.
Having learned a lot more about this over the past few weeks, I think that all these parts are designed to work together as a system, and to lighten the trigger pull, you need to replace both this small coil spring, and also the gun's Main Spring. I just got one of those kits from Brownells, which says right on the package "Designed and custom made by Walter Wolff".
In my case, I'm not going to do anything about this spring kit right now. I just got my gun re-assembled, and now that it works better, I want to see how it performs with all the "stock" parts, just as it came from S&W before I change anything.
The answer(s) I'm looking for, are how to go about using these spring kits, including:
Please correct anything that I've said which isn't accurate. I probably won't get around to actually doing any of this for a few weeks, and I haven't been able to find a good article on the internet or the books I already own, that suggests how to do all this....

The answer(s) I'm looking for, are how to go about using these spring kits, including:
- If you ask a support person for assistance as you order a spring kit from Brownells, he will ask what you're going to use the gun for, as there are spring kits in various strengths. I avoided the extremely light strength set, as the tech person suggested it is only for experts, which I'm not.
- When installing the kit, is it best to initially only replace the coil spring, and only if desired, also replace the mainspring? Or should you replace both at once, as they're designed to work together?
- The Brownells kit came with 13, 14, and 15 pound rebound springs. Is it a good idea to start with the 14 pound spring, and then make a change if needed?
- I assume the "strain" screw will be tightened down all the way, tensioning the mainspring, so that will not be an additional way to adjust the tension.
- Lastly, I think I understand that none of these parts will make much of a difference, if any, in shooting SA, but will only be noticeable in DA.
- All these custom coil springs, and the stock S&W springs, have the ends finished: there is a flat surface at the end of the spring. If you cut off a coil, you no longer have that flat surface. Is this a good reason to avoid cutting a spring to make it "softer"?
