Every time I move cylinder release lever on my 627 I see Lock flag moving up and even when I do release the release level I can still see the flag, even if barely. I'm curious if this is normal.

Pictures are attached.

sw1.jpg shows the cylinder release level depressed and the flag high enough to be able to read the text.

I only have one Smith with the lock, a 629-6 and it looks like your first pic all the time. Never moves any.

Fwiw, My 629-6 the flag moves ever so slightly when the thumb lever is pushed all the way in.

It should look like in your first picture all the time. There's a small spring (inside) on the mechanism. I wonder if it came loose?

Have you tried to operated the lock with the key?

I've just checked two of my S&Ws with the lock and the flags don't move on their own when I push on the cylinder latches.
I then used a probe to pull up the flag and there was just a tiny amount of spring pressure which brought the flag back down if pulled up.
I'm not well-versed enough to disassemble the lock-work in my external hammer S&W's any further at this late hour as I've got to be somewhere for work in the morning. Also, I've never done a full detail strip and there's always that possibility I'd never get it back together.

Perhaps someone else with more knowledge of that lock with the indicator flag will answer soon who can definitely diagnose your issue.
I'm suspecting that flag is either broken or not perfectly assembled to provide that spring tension to keep that flag down until the key is actually turned to bring it up.

I'm curious, too, yet glad my guns aren't doing what yours is doing as it doesn't seem right. I'll go look at some Youtube videos next to see if somebody is shown completely detail stripping that lock area. I'll subscribe to this thread for my own edification.

OK, go to ~5:09 on this Youtube vid and see how the little spring on the flag should be placed. I'm guessing either that spring is broken or just out of place. You'll need to dissemble to the point of getting the bolt out of the way to access the flag & spring.

The vid is of someone working on a 640, which means there are a few less parts compared to an external hammer model, which makes things slightly easier for that guy.

Install "The Plug" and forget about it.

My lock fell out. Oops.

I have talked with my gun smith about the IL. He told me he has worked on a lot of them. The main problem being the spring in lock is either to weak or to strong. The trick is to find one that is "just right".

Ah - that would be the spring for the Goldilocks!

My R8 did that. Doesn't matter, I remove all flags from my newer Smiths.

Just 'Plug' it and forget it!

Not normal. My 629 did the same thing. Sent it back to S&W and it was fixed when they returned it to me.
