Could anybody tell me about the functions of the HAMMER BLOCK.
I think there is the Hammer Block feature on my S&W 60 - I would like to know how it works. I was trying to find info at S&W website but I didn't find much about this issue. ???

Thank you!

The S&W hammer block is a safety device.
It blocks the hammer from hitting the primer (or the hammer from hitting the firing pin over the primer in current guns) unless and untill the trigger is pulled all the way back. It guards against accidental discharge if the gun is dropped, hit on the hammer, or if somebody monkeys with it and slips the hammer.

This is just the opposite of the transfer bar used by Ruger, which rises to connect the hammer and firing pin only when the trigger is pulled.

Look at this link. Scroll down to the revolvers and all will be explained.

Google works wonders

I looked inside the hammer window of my S&W 60 but I don't see nothing like that or any moving part that stop the hammer from hitting the primer when I pool the trigger... Huh!!!

the hammerblock is located inside and rides up and down based on trigger position
when the hammer is pulled back the hammer block drops down, when it is down the block rides up and gets between the hammer and firing pin, to hold the hammer off the pin. you will have to take off the side plate to see it. Unless you have done this before I would not recommend doing so now. The hammer block has to ride in a slot on the sideplte.

Some S&W revolvers don't have hammer blocks (the 642 doesn't, for obvious reasons), but a lot were taken out by owners who thought they interfered with the trigger pull. So if the Model 60 really doesn't have one, it has been removed, and I would replace it.

Take another look at that gun. Make sure the gun is unloaded, then cock the hammer and look in the gap in front of the hammer. You should see a rectangular piece of steel in the front below the point the hammer would hit. You should be able to release the hammer and let the trigger go slowly and see that block move up a little before the hammer blocks your view.
