S&W 317 question

I have a S&W 317 2" Airlite 22LR revolver. The trigger pull is very heavy. I understand that Wolff sells springs for this model but they have a variety and I don't know which one is the best for both a lighter trigger pull and still keep enough strength for consistant firing pin hits...any suggestions?

  If none of our folks can help you might consider posting to the Rimfire Central site, they have a very active S & W forum.
  
  There is also a separate strictly S & W Forum site but the times I have been over there most of the discussions concerned the larger centerfire S & W handguns.

  I always start here with a question then move to the more specific sites like the ones you mentioned in your reply....I used to point other posters to useful web sites on this forum as well, but a moderator sent me a nasty "don't recommend other web sites" admonishment when I suggested the usefulness of other expert collector locations for model variation checks etc...

  I own a 17-9, and indeed, trigger pull is rather heavy. Therefore, I replaced the springs, and polished the action.
  
  You need to get the spring set from Wolff or Wilson Combat. They come with one lighter main spring and one each 12-13-14# rebound coil springs. You may also consider purchasing along a medium India stone, and a rebound slide takedown tool.
  
  Lighter springs may actually worsen the problem unless you stone the action (several videos are available for this purpose at Youtube), so as long as you stay away from the SA sear, you'll be OK.
  
  After you polish the action, swap the main spring and the rebound with the 12# spring. Reassemble the gun and work the trigger. If the 12# is not heavy enough to return the lockwork back in place, try then a heavier spring.
  
  Hope this helps.

  Jorge's advice is spot on.
  
  But, if you have never R&R'd a S&W sideplate, it is a scary procedure the first 10 or 20 times that you do it. Make a slight mistake (like, us a screwdriver for a pry bar), & you can ruin the gun.
  
  If it were me (well, actually, it was me), I'd pay a gunsmith; not a difficult job for him.

  Thanks for the advice...I'll send away for the Wolff spring set and see which spring weight gives me the best performance. I wasn't sure which spring would work best in the Airlite 317 frame.

  As nmyers stated, a critical part is the side plate removal.
  
  First, make sure you have the right sized screwdriver, otherwise, you'll bugger the screws. Afterwards, don't use the screwdriver as lever to pry the plate, but rather use the handle to rap several times on the grip until the plate comes off.
  
  As far as stoning the action, as I previously stated, just stay away from the single action sear, and you'll be safe.

  I just ordered the Wolff spring kit, but couldn't locate the India polishing stones...any suggestions on where to locate the right ones?

  Brownells is the primary source for gunsmithing tools and repair parts. They have a large net site with a extensive on-line catalog.

  I found the stones on Brownells but was confused about whether Arkansas or India style stones are best...any opinions?

  Arkansas is more fragile.
