I think the thing to bear in mind is that the essential similarity between a striker fired pistol and a single action pistol is the 100% consistency in trigger "press". Whether you look at the striker fired gun as a short double action, think of it as a DAO, etc., the key is that you do not have to train for two distinct trigger "pulls" (press - pull, whatever word you like). For many shooters that is a distinct advantage.

I will not wax eloquent on my preference for TDA pistols with decockers (think 3rd Gen S&Ws). I shall save that for other threads. Striker fired guns are not usually my cup of tea.
