My mind is living on cloud 9 and this nine is never on vacation
Kendrick’s mind is in a state of happiness and his 9 mm handgun is works overtime and never takes a day off. This could also be a metaphor as his mind works as a handgun and he can completely turn from a side of happiness to an angry vengeance seeking side.
(On a side note Kendrick made a song called “Cloud 10”)
This line might be related to the 1st one too, Kendrick is living his dream and reaching his goal, he feels so good that his mind is in a state of happiness, but there is struggle everywhere. The human contradiction (good/evil, red pill/blue pill) once again.
