325/329PD question?

[xrmattaz]

Removed the lock from both of 'em today, everything went well. In examining the inner workings of these two, though, I'm wondering what the transfer bar actually does....if that is the correct term?

Does this bar somehow block the hammer from hitting the firing pin, if the revolver is dropped, or (?), as I would imagine it's role to be.

My terminology is likely wrong, can someone explain?

A transfer bar would transfer the force of a hammer to the firing pin.

I think the new smiths, like the older ones, have a HAMMER BLOCK.

A HAMMER BLOCK blocks the hammer from striking the firing pin when it's in the way. The hammer block is held out of the way by the trigger mechanism when it is held back. If you un-cock the gun, by holding back the hammer, and let go of the trigger as you let the hammer back down, you'll see that the hammer does not push the firing pin forward.

If you un-cock the gun and hold the hammer down, you'll see the firing pin gets pushed forward.
