Just bought a new 6" 617 Friday and took it to the range today. Put fifty round through it and I'm very pleased with the accuracy. However, the single action trigger pull is not as light as my 686. What can be done about this. Will it get better over time. My Model 63 has a better single action trigger pull also.

The easiest way to get a lighter trigger pull in a 617 is the replace the trigger return spring with one of a lighter weight. Brownell's has these.

You might want to leave the mainspring as it is. Rimfires require a good firing pin strike for best results. Most of the excess trigger pull weight is from a too heavy trigger return spring.

This is not really all that easy to replace if you have not done this before. You might want to consider a pistolsmith.

FWIW

I would hold off for a while because the trigger will smooth out some after it's been fired several hundred times. My first 686 no dash was a lot smoother and lighter after about 300 rounds then when it was new. The other way is to take it to a gunsmith and have him lighten your trigger pull either through a different spring or a trigger job.
 
1) If you haven't yet, try removing the grips and adjusting the mainspring's strain screw.

2) If that doesn't satisfy, try a Wolff Factory Standard Mainspring Type 1 (not Type 2):
Springs for SMITH & WESSON Revolvers Easy install and a significant improvement.

3) In either case... Follow with 5K dryfires w/ snap caps! (thumbs up!)

:) New S&W revolvers come with out oil on the internal parts. I would get some oil in there. This should also help. Don
 
If #1 doesn't satisfy, and you want lighter and smoother...


I ordered and installed this with excellent results (and I mean my trigger is now light and smooooooooooooooooooth):

Wolff's Shooters Pak (SKU 17120): "...Power Rib mainspring and 1 each of 13, 14 and 15 pound reduced power rebound springs allowing optimum
adjustment of the hammer and trigger functions. These paks can often take the place of expensive "trigger jobs" with better results.."

I don't know how much the Rebound Spring itself improved the trigger, because I replaced both at the same time.
Replacing the Rebound Spring is a bit more difficult than replacing the Mainspring (which is simple), because the screw to remove the spring
is under pressure from the spring itself. Exercise caution, and you should not have a problem. You can order a special tool made specifically
for installing this spring, but I didn't need it. I went with the 13lb spring first, and I have had no issues.

I had no experience with S&W revolver internals prior to doing this. However, I had an experienced mentor looking over my shoulder and giving me tips.
If you do not, I would recommend:

1) A set of gunsmith-quality screwdrivers
2) This video: Gun Video "Trigger Job: Complete Action Tuning for Smith and Wesson Revolvers with Jerry Miculek" DVD - MidwayUSA
