I have a few of the older Smith revolvers. I used to do a little trigger work on them. Really easy to get a great pull. Have a 586 somewhat like yours but it is tricked up a little.Did some trigger work on it and can say it has the best trigger I have ever used on a handgun..even in double action. I also have a late 60's Colt Python. 3 inch bbl but it really does have a pretty good trigger for a factory job. Pretty blue back then too. One of those guns I ought to sell as I hardly ever shoot it.
