Spring kits are not really a big deal. They do make a lot of difference. But as others has said practice is the key. That being said I would not own a revolver that had a 14 lb double action and 5 lb single action pull. Ther is really no reason for it given the parts available and the instructional videos and gun forums for direction.
I had never unscrewed the side plates to any revolver prior to this year. I have now installed 2 spring kits, 2 extended firing pins and polished a few parts of the trigger.
I know there are other kits out there but I would buy the Wilson Spring Kit and the extended firing pin for your particular revolver from Brownells. Follow the Gary Miculek video (search youtube) on how to install the springs. It is pretty easy. The firing pin can be replaced with a pair of needle nose pliers. PM me if you have any questions on that. With the reduced mainspring you can get some failure to fires.
1. Order a Wilson Spring Kit
2. Use the 14 lb return spring ( the kit comes with 12, 13 and 14 but 12 and 13 seem mushy on the return)
3. Get a good set of hollow ground screwdrivers.
4. Order an extended firing pin from Brownells as well.
5. Have a good set of needle nose pliers and tweezers.
6. Take your time and follow the instructions. If you have questions post them in the gunsmithing forum here. You will get loads of help.
7. A good quality trigger pull gage is helpful. I have the lyman and it is pretty reliable and repeatable.
This will only reduce the spring tension and the trigger pull. It will not smooth out any rough spots or make the action smoother. I had to dry fire (with caps) my 629 about 2k times but it got rid of the creep and rough spots. The only other option there is to have a gunsmith do it. You will be amazed at how nice the gun shoots. Practice is still necessary but it is alway nice to have confidence that your equipment is functioning at its best. Good luck and email me if you have any questions
