It is difficult to answer your question without more information. Answers to the following questions would be helpful.
- What is your previous experience working on revolvers?
- What is your intended purpose for this revolver?
- What is your goal for the project? For example, is your goal to learn about revolvers? Does it have to be done right the first time?
Let me give some explanation. My general answer to your question is "Send it to a gunsmith with expertise on revolvers." If the gun will be used for any critical purpose, and if you want it done soon and done right, then it should go to a pro.
If you have some experience working with guns or other fine equipment, and you would enjoy having a project where you learn about revolvers, and it is not critical for the revolver to be reliable any time soon, then doing it yourself is a reasonable option. If doing it yourself is a fit for your goals and requirements, then this forum can offer lots of additional advice.
You may get suggestions that a certain spring kit will give an excellent and reliable trigger, but revolvers are trickier than that. Many people have installed a spring kit and done a little bit of polishing and gotten good results. But many other people have tried the same recipe and gotten misfires or other problems. Sometimes the problems are subtle, so the gun seems OK for a while, but then problems become apparent later.
I am always happy when people get good results from a spring kit or other simple changes. But I think some of the posts about these successes create an overoptimistic impression about working on revolvers.
If you provide some more information about your requirements and your goals, I am sure people here can provide some more specific advice.
