Hello guys, I just did some tuning on my S&W 659 that I want to share with you, in case you have a similar problem.
When the hammer is cocked, the trigger has some play, which is normal. What wasn't normal was that the play on the trigger was VERY gritty, like there was sand in there (there wasn't, I field strip and clean my guns after everytime I shoot). After months of ownership, I finally decided to take the whole gun appart, which I had never done on a semi auto before, just revolvers.
After some investigation and trial, I found out that there were lots of machining marks on the bottom of the hammer, where it rubbs against the very tip of the draw bar. This was not the area were the draw bar pulls the hammer, to be clear. I very carefully went at it with some 400, then 600 grint sand paper, being careful not to remove much metal or change the shape. I made sure to not touch either one of the hammer notches, or to change the geometry in any way. I do have some experience fitting parts on my other guns, sanding, polishing, etc.
I put the gun back together and voila! the grittyness was gone. I cycled the action some and put it back together. Since I didn't touch the notches or the sear, the hammer engagement was left intact. I think I just saved a bunch of money not going to a gunsmith. I am not saying you shouldn't go to gunsmiths, but that some of the work can be done at home.

It's an accurate gun :)
