Favorite pistol Action?

[MT2008]

I understand the appeal of either SAO or DAO, but I personally like SA/DA. I think having the option to choose is nice.

On the other hand, for conceal-carry, then obviously DAO or striker (and preferably the latter) is preferred because you don't want the gun to snag. But some pistol designs are shaped in such a way that this is kind of a difficult goal, hammer or no hammer (like SIG's "SAS" models, which I personally don't like).
