I brought home my new 642 yesterday and my wife asked me a question that I really couldnt answer. She asked me if there were any safety features on the gun other than NOT pulling the trigger.
I didnt really have an answer for her.
Are there any that I dont know about?

BTW.....I got one without the trigger lock.:D
 
Hammer block, and a relatively long/heavy trigger pull. The rest of the safety issue is up to her.

That's the beauty of a D/A revolver...

Not to frighten you, or anything, but the shrouded hammer models like your 642 do not have the internal hammerblock common to all of the other(modern) models with exposed hammers. Since it's shrouded, it's not subject to any bump or blow which could overcome the internal rebound-safety. The latter is engineered to keep a large gap between the face of the hammer, and the rear of the firing-pin. It's still perfectly safe, so there's nothing to be concerned about.:)
 
I guess you could still call that the hammer block. The fact that the hammer cannot get hit because it's covered up - blocked. :)

On the regular hammer model Smiths the hammer block in interposed between face of hammer and frame while hammer is in rest position. When trigger is pulled, the hammer block is cammed down by a pin on the trigger allowing the pin to reach the primer when the hammer drops.
 
"cammed down by a pin on the trigger..."

Sorry, that's not the case.

The hammer block loop rides over a pin on the side of the rebound slide.

When the trigger extension pushes the rebound slide back, the hammer block is drawn out of its at-rest interference position between the hammer and the frame.

When the trigger is released, the rebound slide moves forward, and the pin on the rebound slide cams the hammer block back into its interference position.

At rest, the hump on the top of the rebound slide rests underneath a hump on the hammer assembly.

The two opposing humps prevent the hammer from moving forward.
