This part is staked into the frame from the inside and keeps the cylinder from sliding off the yoke when the cylinder is open for loading/unloading. Anybody know what it's called?

Hello Texas Roots,

The part you are asking about is called a frame lug.

Take care,

Do you mean the frame lug?
got beat to it.

kanhunter and stbryson, many thanks for your replies. I have a 25-2 that has the "frame lug" that is not tall enough....the cylinder is beginning to slide onto the top of the lug. So I'll need to get this fixed. Thanks again.

You might want to check for a bent yoke. This may account for the cylinder riding up over the lug.

Bent yoke is much more likely than a short lug. Not impossible though.

Hey thanks guys....the problem stems from a refinish done by S&W a few years ago. I think they polished the lug off a little too much accounting for the cylinder trying to ride over it now.

When I got the gun back from S&W after the refinish, I noticed how "short" the lug was then, and the cylinder was very close to riding it over then.

And ever since, I've put at least a couple thousand rounds through it, it is just gradually getting worse.

If you watch the cylinder/frame lug interaction as you swing out the cylinder; a bent yolk can be indicated by a change in the amount of overlap of the lug over the cylinder breech after the center pin has cleared the frame.

I know, I know, You want to say- huh?

Is there a single place in the cylinder swing out where the cylinder wants to over-ride the lug more? If so; a bent yolk needs to be check for.
