Donald, yes according to Kimber -- "In many respects a miniature 1911, among the most important Micro 9 design advantages is a single action trigger with the kind of short, smooth pull that ensures accuracy and builds confidence." Have a great day!

yes it is a single action based on the 1911 single action

This is a single action pistol. Hope this helps.

Donald, yes Sir. Single Action with no re-strike capability until the slide is racked again in case of a mis-fire. Cheers and stay safe!

This is a double action only. Buds product description guy isn't the sharpest knife in the drawer.

Yes, the hammer must be cocked in order to fire as with nearly all 1911-based designs. It is almost a non-issue as the hammer will always be cocked simply by chambering a round unless you manually decock it by pulling the trigger.
