A rebound spring"guide rod" in my 696???

[Rule3]

When replacing the mainspring and rebound spring with the Wolf spring kit, I found what looks like a small guide rod/pin in the rebound spring?? I left it in but I have not seen this pin before in my M 66, 686 etc.

I looked at schematics and it does not show it??

What is it and why??

That is a trigger stop.

Thanks

Is that a "custom" or optional part? On the schematic it is listed as a 999 part number.

As a stop, does it make for a shorter pull and faster return or something??

Last part on the bottom.

It reduces trigger over travel. I make them using a drill bit for stock.

Thanks. So the previous owner of this gun installed it? It's not a standard factory part is it??

They were install on most of the newer S&W revolvers from the factory.

N Frames had them factory & as others said can be made from drill stock.. Note that it should have a rounded end a flat end..
The rounded end goes into the rebound slide & the flat end towards the pin..
Pretty Sweet Addition to S&W..

I thought I had read that the factory did install them on certain guns. I may have confused factory with Performance Center.

I think I put it back that way I shot it yesterday and it works fine and didn't go full auto so I guess it's in right

I'll have to look at my 629 and see if it has one. The trigger on it is fine so I never messed with it.

I'll be durned, didn't know that.

I still do not get the purpose or the way it functions? The rebound slide has the slot in it and doesn't that determine the max amount of travel? Unless this pin stops the travel before the slot??

The slot does not limit travel. The trigger stop rod does limit travel (most are fitted "too short") if one is installed, if no rod is installed, the trigger usually stops when it hits against the frame. It seems potluck which guns have stop rods. If you order a stop rod they need to be fitted, trimmed to length, thru trial and error.

OCD1, it's real easy to see the difference. Remove the rod and test it by dry firing it, you will see why it's placed there. It's a poor mans trigger stop, compared to the performance center triggers where they fit a external screw behind the trigger so the whole world can see it.

I will do that. I just finished changing out the springs in two more J frames, so might as well pull the 696 apart again. I really do need to check if I put back in correctly.

Thanks

In case your not sure, the flat side of the pin goes against the rebound block stud.
Round end fits inside the block.

I took it apart again and did have it installed correctly. There is not much difference between the "flat" and "round" end. I think this may be a homemade pin. I tried with and without and really cannot notice any difference.

The Wolf standard power rib mainspring and reduced power rebound spring made a big difference and the trigger is just fine for me now. Fired my handloads using Wolff primers which are pretty hard, so I am happy with it.

Thanks for your help.
