Revolver Guru's - What's this for on my revolver?

[NitroX]

This little nib sticks out on my older revolver. What's it for?
When the cylinder is open it spins freely BUT if it's loaded and open then the rim of each cartridge rubs up against the nib on the side of the gun, so must be a reason for that?!? To load it without the cylinder spinning freely? -or- to keep people from playing Russian roulette since the cylinder won't free spin when it's loaded because of this nib?

I might also add that my newer revolver has no such nib on it so why the change?

Probably to keep the cylinder from sliding off when it's swung open.

That was my 1st thought too, but the cylinder won't push up against it even if I try. Maybe it's for that if something else fails.

Rossi?

Is that a Charter Arms?

It keeps the cylinder from being pulled off towards your hand when the cylinder is open.

I belive its the rebound slide pin on an older rossi or taurus

i think my S&W .38 special has the same thing..ima have to check it out, i would also like to know what it is for

 

[dwr461]

I've looked through both of my Colt shop manuals and so far can't find that piece referred to anywhere. However I should mention that on a Colt that bump comes off with the side plate unlike the S&W system. There are many people here who know more about this subject that'll be along to help directly I'm sure.

Hey Dave,
Yes, it's Charter Arms.

If I'm not mistaken, it's called a cylinder stop.

I've pretty much come to the conclusion that you're my gun knowledge hero. Seriously.

Looks like a gizmo to me. Probably works some kind of thingamajig.

I got a charter, it doesn't have that.

How old is your gun?

What he said, if you hit the cylinder hard enough on a reload you can flex it that far, trust me i have on an n frame.

 

[bhp9mm]

what they said it keeps the cylinder from felling off and the name of the part is cylinder stop stud
