I found an extra part after cleaning my 625JM

Goes inside the spring in the rebound slide
Correct. It is a trigger stop, to limit your over travel during single firing firing.
The good thing is it's big enough to see (and find if you drop it). Try finding sometime that tiny lanyard pin loosely fitted under the rubber grips of the aluminum frame J- magnums. I was ready for them on my new 340s. Put them aside in a small plastic box. Makes the guns lighter to carry...

It appears to be a .45 ACP ball round. It goes in one of the chambers of the cylinder. Don't worry, we were all new here once.

Now THAT is funny.
Thanks, so that pin rides inside the rebound spring.
You got it!

If that is the Trigger Stop Pin you will find this pin also has to be installed correctly. Look closely and you'll note that one end features a bevel. Install the trigger stop pin backwards and you'll find the trigger locks up solid when the revolver is held in certain orientations. What happens is that if it's installed wrong the sharp corner at the end of the pin "snags" on a coil on the Rebound Spring and locks up the trigger.
Sorry but I cannot tell you which orientation is correct, I've gotten it wrong so many times that I now use my Dremel to put a small Chamfer/Radius on the corners at each end so they are non specific for orientation.

The bevel end should be towards the rear of the rebound slide spring assembly. The flat end up front. Some are beveled on both ends.
I don't take apart my revolvers (do all sorts of other dangerous things instead
), but this is a helpful post. Even includes info on how to get around the difficulty!There are moments when I wished I knew more about tools other than those on a Boy Scout knife. Moments...

Thank you all, the gun is back together and I learned somethings.
I learned something foolishly removing the grips from a Baby Browning .25 and losing a tiny part I never knew the name of. I learned never to take apart a gun I could not re-assemble. There are also some folks who take apart revolvers almost daily either for fun or just because they can. I've also learned not to do this.

Yeah, I'm wondering why the OP felt the need to do that in the first place not knowing what he would find inside? Worse still how to put it ALL back
I've owned S&W's since the 70's and the only times I open the side plate are:
1. Do trigger work
2. Fix or replace something
3. Clean if it's been a L-O-N-G time
4. MAYBE if I just bought it and it was used

Glad you found the part and we able to reinstall it.
Every time I disassemble a gun for the first time, I do it inside
a two gallon zip lock bag. That way if anything goes "BOING"
all the parts are in the bag.
