686 pro series trouble

The trigger’s not fully returning and engaging the DA sear. First thing I’d do is a good internal cleaning & lubing. If you swapped springs to lighten the pull, chances are you put in a rebound spring that’s too light for the mainspring. Got a trigger gauge? What are the SA and DA pull weights?

Could be a broken DA sear spring?

Just send it back to Smith and Wesson I have had nothing but great customer service from them on a 642 I screwed up. They fixed everything and send me a label to get the gun shipped, everything was on their dime.

You are not fully returning the trigger forward before you pull it again.
When you took off the sideplate what tool did you use?

odsixer; Look at this https://www.brownells.com/schematics/smith-wesson-/l-frame-686-sid557.aspx
The bottom of part 49 rides on the top rear portion of part 69 while you are pulling the trigger. Part 49 is spring loaded and should slide to the rear of part 69 as you allow the trigger to return to battery.

Check to see if that is working as it should.

My guess is that it comes back with a nice trigger job for your troubles. In my (recent ) experience it will take 4-6 weeks though.

Howdy

Is this your first double action revolver?

Before you send it back, make sure you are releasing the trigger all the way before pulling it back again. Sometimes guys who are used to semi-autos don't realize how far a double action revolver trigger needs to travel forward to reset for the next shot. Practice completely letting go of the trigger before pulling it back again and see if the problem goes away. If that solves the problem, eventually you will learn how far to allow the trigger to travel without removing your finger from it.

Did you try my suggestion of making sure you completely released the trigger, and seeing if it solved the problem?

Master Blaster wants to know if you pried the side plate off.

Yes, proper technique involves quickly & fully releasing the trigger, but the trigger on a properly-functioning revolver should fully & consistently reset no matter how slowly the trigger is released. Could be something simple, like a DA sear that’s a whisker too long, but your best bet is to send it to S&W.

This is correct. Watch this video of my with my 686-6:

If you ride the reset, it will fail. If you release the trigger slowly, it will fail. After I discovered this, I tried 3 more at the LGS. All the new 686s I tried showed the same symptoms. If you want it to be reliable, either send it back to Smith or slap the trigger around like a 12-year old with a 10/22. Mine will be going back...revolvers should go bang every time, this one does not.

And yes, that scratchy finish was on the gun when I got it, and the others too. I'll polish it after it comes back.

Really?????
