S&W Model 629 Classic?

[G11354]

I'm looking into purchasing a model 629 S&W revolver and was wondering if the hammer has any type of safety to prevent a round going off should someone accidentally strike the hammer with something?

Yes, all modern S&W's ever made have an internal hammer-block safety that positively prevents the gun firing due to an impact on the hammer.

No concerns there at all.

They will only fire if you pull the trigger.
That lowers the steel bar hammer block out of the way so the hammer can strike the firing pin.

If im not mistaken isn't the firing pin on the hammer on the model 629?

The old ones were.

The new ones aren't.
FP is frame mounted now, starting in 1997.

Since 1945, Smith @ Wesson revolvers have had not one, but two, independent safeties. The first "rebounds" the hammer, causing the hammer (regardless of where the firing pin is mounted) to rotate backwards behind the breech face. It then blocks the hammer from moving forward. The second moves a steel block up to just below the firing pin and places an additional restraint to prevent the hammer from moving forward.

Unless someone has tampered with the system the cylinder can safely be loaded with all the chambers filled.

The only exception I'm aware of is those models with a fully enclosed hammer, in which case the second hammer block is eliminated because with the hammer fully covered by the frame it's unnecessary.
