I've managed to pick up three DAO Smiths, a 4046, 6946, and an NYPD 3914 DAO. I like the smooth slides and DAO in a defensive weapon makes sense for the consistent trigger pull is very revolver like.

No chance of an engaged safety in a stressful situation. A shorter and lighter DA trigger pull with the DAOs is an advantage too. Second strike capability in the 3914DAO is also a plus.
