Need help!! 327 TRR8

[swtsrhaz]

Hi guys, I have a Smith Wesson 327 TRR8, and when I took it apart to clean it, a tiny spring came loose, I have no idea where it came from, and I watched countless videos online and checked many websites to look at all the different parts, and I can't find anything that matches it. It looks almost like a smaller version of the hand torque spring that go inside the trigger, but it's much smaller, and I can't figure out where it's suppose to go. Does anyone know what this spring is and can tell me how to install it back?
Thank you so much

That looks like the lock arm spring.
I don't have a flag taken apart, but you can Google it. On how to slip it back in.

So just remove that safety flag would like to do that for my 340

Sear spring. They use to be pinned in place. They're a real bear to reinstall.

FYI once you get it back together and functional, understand detail disassembly is NOT needed to clean a revolver, in fact no disassembly at all. Certainly not removing the side plate or internals.
I buy all my smith and Wesson revolvers used, pop open the side plate to inspect degrease and clean one time. Then seal them up again forever.
