Subject: prevention of accidental discharge via a blow to the hammer. Ruger NEW revolvers have the transfer bar safety system (doesn't Taurus, too?).It's easy to explain and actually see how it works (you can see the transfer bar). So how the heck does my SW 629-3 have a safety feature built in? Does anyone understand it? Here's how it appears: after pulling the trigger (on an UNLOADED GUN), when you can see the hammer depressed all the way, upon release the hammer travels backward away from the pin. Does this imply a blow to the hammer cannot set off a round? Sorry for the long question....

Revolver Safety: Ruger vs. SW

If you look closely you will see that S&Ws have an internal hammer block which drops down out of the way when the trigger is pulled. When the hammer is at rest, it blocks the hammer from moving forward far enough to contact the primer. In short, its perfectly safe.

Both of the above postings are correct, just not complete. Taken together, they describe the safety mechanisms in an S&W revolver.
These two work in the following manner.
1. The rebounding hammer. When the trigger is released, spring pressure forces the hammer back to its at rest position. At the same time, the rebound side (which is directly linked to the trigger) moves forward into its resting position.
On the rebound slide is a "hump." This hump comes to rest under the front lip of the hammer, preventing it from moving forward.
2. The hammer block is a secondary mechanism. It is an L-shaped piece of metal that is attached to a stud on the rebound slide, and moves back and forth in a groove in the side plate. When the trigger is pulled fully back, this is retracted. When the trigger is released, and the hammer moves to its at-rest position, the L moves up and comes between the face of the hammer and the frame.
Even if the hammer is struck with a crushing blow that would somehow cause the hammer to go forward, this L device (I'll be darned if I can remember the proper name right now!) is there to prevent the hammer from moving far enough forward for the firing pin to hit a primer.
