Help with 686 Wolff spring install?

[TriggerHippy]

I put some Wolff springs into my new 686+, the reduced power mainspring and the 14# trigger rebound spring. This was my first time working on my Smith.

Now, upon cocking the hammer I have to apply extra pressure right at the end of the hammer travel and the gun makes an extra little click to lock it back. If I don't do so just right the hammer falls forward.

The only potential issue I noticed while changing the springs is that the bottom of the Wolff mainspring doesn't quite reach into the notch in the frame where the factory spring would seat. If you imagine the notch as the curved part of the bottom of the number 5, the Wolff spring stops at the vertical part while the factory spring seats in the curved part. Maybe the mainspring geometry is off?

This may be unrelated, but I had to cock the gun when putting the sideplate back on in order to get the hammer block to sit in the slot on the inside of the sideplate. Maybe it wasn't properly seated over the rebound slide pin?

Anyway, as I'm sure you can tell I haven't done this before, so any help would be appreciated.

Take it back apart, you have something wrong. I just did a spring install in a 686+ and it went in no problem. Make sure you have the parts fully seated.

I have them in my 686 and 681 and have installed several for other folks. I have never noticed any real difference in the "feel" other than the reduced TP or hammer-cock.

Afternoon TriggerHippy;

First, make sure the little link between the hammer & the main spring is in correctly (might be upside down).

If the link is OK then go back to your stock spring to see if your problem goes away. Might be a mis-manufactured Wolff spring. I have had some problems with Wolff spring quality lately (not the quality they used to be for sure)

Well there's your problem!

Yep, it was the mainspring being slightly too high in the frame to seat properly.

I loosened the strainscrew, pulled the spring down to where it should be, reassembled and -- viola! Action restored to original feel except for the nice lightening of the DA by the new springs. SA slightly lighter break as well.

Thanks for the ideas.
