S&W use a hammer block system. There is a block in the mechanism that will not allow the pointed hammer to protrude thru the frame unless the trigger is pulled. It's a very positive system. the hammer doesn't lock, it is blocked.
Not only. I mean, Smith & Wesson's revolvers had a hammer-mounted firing pin until the 1990s, just for example. Nice pointy thing on the hammer, hole in the frame it goes through, big soft primer on the other side. Sure the hammer has a lock in the rest position, but parts can wear, and accidents sometimes happen to apply much more force to the hammer than anticipated.
You should NOT leave the hammer down on a chambered Tokarev pistol, because it moves freely in the down position, and the firing pin is long enough to contact the primer. Use the half-#### safety notch, or carry it un-chambered.
