340 M&P Yoke Problem

[Wiskey_33]

Hey folks,

just picked up a lightly used 340 M&P.

Went and fired a few mag rounds through it today to see how it felt and as soon as I got home I noticed the yoke stud was coming out of the "body" I guess you could say.

See attached picture. I was able to push it back in. I took everything apart, cleaned it up real good, then put it back together making sure the yoke screw was tight. Before and after pictures are attached.

What's the cause/effect and fix for such a thing?

This is my first .357 J frame, but have never had any issues with the Airweights.

I'm already in discussion with S&W but I hate the idea of sending off a new pistol for a few weeks. Has anyone had any experience with their warranty wait times lately?

Thanks folks,
Wiskey

Perhaps the screw was just loose.
If everything lines up, go have fun and keep an eye on it.

That part should not be loose. You need to Locktite it or pin it or both. You could put a blind pin in the back side that would never show with it closed.

S&W is sending me a shipping label. I'm going to send it in and let them fix it.

Cheers.

Smart choice. That's what lifetime warranties are for.

[Protocall_Design]

Yep. Best choice in this case.

From your picture, it can clearly be seen that the crane plunger has gouged a big divot into the crane's recess area where it makes positive contact to hold it tight. With the metal no longer there, the crane is not held tight and can move.

Most likely because of the 'airweight' metal design. Doesn't appear that strong unless they forgot to treat the crane. Send the gun back, because S&W will have to replace it.

Thanks folks. I'm sending it in. I've also noted the issue of very little frame lug/cylinder contact when the cylinder is open. I'm surprised I can't pull the cylinder off when open.

I'm wondering if they're going to replace the frame or give me a new gun.

Anyone have any experiences with S&W in that regard?

Based on my own very limited sample set, I would say that Smith & Wesson is not stingy about replacing the frame. They will make an assessment about how to return the gun to top condition. And if they can do that without replacing the frame, they will do so. But if the frame needs to be replaced, they will not be hesitant about it.
