A quick note: the prior reviewer misread the Anthem Gunner. As written: "If an anthem gunner fails to sing or make an attack with her firearm while her song of strife is active, it immediately ends, regardless of its remaining duration." This ability ends if the anthem gunner does NOT fire that round.
Otherwise, though, the Legendary Gunslinger class presented in this book is 3/4 BAB (instead of full), and gains Gun Mastery abilities, which are feat-like functionalities that make the Gunslinger even *more* the master of the gun.
This book is a must-have for anyone who loves the Gunslinger class.
