Anyone ever see a revolver do this? (UPDATED) X2

[jimandsue60]

What is the part of the gun that I have highlighted? My 340 PD does not have that nor do any of my other S&W revolvers. It seems that that lines up perfect with the marks on the cylinder. Or is that the corresponding wear mark on the frame?

So lets conclude, that it is the hole near the breachface, where the center pin goes into. It may elongated.

I see what you mean. The line on the frame just in front to fht bolt matches thre lines on the cylinder. My 642 does not show anything like that. I have no idea what is causing it, unless you have a high spot somewhere. I'd discuss with S&W customer service.

Pictures of fish, dogs, kids, boats, motorcycles? Just what kind of pictures do you want... D)

there is a "ding" on the crain by the cylinder. Looks like something is moving that shouldn't. MHO Bob

I think you guys are looking at the wrong marks.
Look between the cyl flute and the locking notch. The frame is marked at bottom right in front of the cyl stop.

Strange- I've never seen that.

You're right, I missed that altogether. I've never seen that either.

If the pin hole at the rear of the frame was elongated, then I would expect to see the same type mark on the rear edge of the cylinder, since if the rear is moving down, then the rear most edge would be moving more than the rest. I have a 57 with similar markings and discovered that the cylinder holes where bigger at that point, ie the cylinder was bulged. It was not touching the frame except when firing apparently. So I'm gonna go with a cylinder that is flexing on firing.

The potential good news is that since it's an IL revolver, there shouldn't be any difficulty getting an exact replacement if need be.

I was not able to call S&W customer service today but I did get a few more photo's.

I had not noticed the marks behind the cylinder lock before, it does look like the whole cylinder is pulling back and down during heavy recoil.

If Smith wants to replace it I will get something similar and do more +P and less full power.

That's odd indeed. It appears as though it is pivoting downward along the axis. Curious, are there any marks (besides the carbon) at the top of the frame by the forcing cone?

 

[roundgunner]

It looks normal to me.

It maybe the crane flexing.

 

[Invictus357]

A fascinating (yay for you, right?) problem that has many here intrigued.

Have you tried pushing the rear of cylinder downwards when the cylinder is closed? If it's rigid, try doing it with trigger pulled back. Unloaded of course!

Can you flex the cylinder at all when it's open? I wonder if the cylinder crane has an issue.

Did you notice the rings of the casings on the back of the frame? I've never seen that before either.

More evidence of the cylinder slapping back and down when firing.

edit: Look very close at that picture of the back of the frame. That dimple where the ejector star nub sits (pardon my incorrect terminology)...looks like a wear line going downwards.

The case head marks on the recoil shield are normal, but those on the cylinder and bottom of the window definitely aren't.

I just looked at my 360PD. There are no marks on the frame or cylinder like yours. I shoot full house 158 gr .357 magnums. There has to be excess movement or a bulged cylinder to allow that. Looking at mine from the side, there appears to be approx 1/16th clearance between the bottom of the cylinder and the lower frame, perfectly parallel along the entire cylinder length.
What does yours look like from the side?

S&W is sending me a lable.

 

[pill popper]

So,the cylinder is bulged? If thats what I'm seeing, any ideas why?

Or is it just out of round??

If this pic shows the cylinder is locked up,
it is between chambers.

 

[P95loser]

I am by no means an expert but using the naked eye there doesn't appear to be anything that could cause that! Please let us know what S&W tells you!

As they should....but shame on you for actually shooting a lot out of a carry much shoot seldom gun.

As fascinated as all...looks to me like the cylinder is pitching upward. Either wear or something not fitted right in the first place.

Especially as not a fan of the other than steel cylinder movement I'd really be interested in this plays out with Smith.
