It triggers anytime you don't land a hit, yes. So if you roll all blanks OR you roll hits and he evades them, both are situations where your attack did not hit and the Gunner will trigger. Technically it triggers after the defender rolls and the attack is resolved, but realistically if you roll all blanks then a defense roll is usually not needed and you can just use your Gunner right away for that 2nd attempt.
