The pre-TSW DAO trigger is really nice. The slide sets the hammer to have cock when it cycles, so the trigger pull fires the gun from half-cock. That means you can't second strike in the event of a misfire, but it also means a much nicer trigger than traditional DAOs. I think its a fair trade.
The TSW DAOs only set the hammer at quarter cock when the slide cycles, so the pull is longer and not as slick, but still without the ability to second strike.
