EDIT: I KNOW PC SHOOTERS DON'T USE TRIGGERS. This is a console question. Think Dualshock controller or Xbox 360 controller. Sorry for the lack of clarification.
EDIT 2:
Let's clarify the question some, because it would seem I didn't think my phrasing through very thoroughly when I posted this...
First- and third-person shooters have, in the context of console gaming, trained us to want to use triggers or shoulder buttons on our controllers to use guns. It's technically more realistic and intuitive, and leaving gun control off the face buttons allows us to use the right control stick and shoot simultaneously, giving us more precise control. It's just natural to want to control firearms and ranged weaponry this way.
Here's what I've found in my studies as a designer: when you make those concessions in a game that you don't necessarily want to fit into a "shooter" archetype--like a platformer or an action-RPG--it inevitably comes to dominate the player's mindset as they play the game. Even if you don't intend for it to be a shooter, it will be assimilated. My question is, then, as to whether or not it's acceptable to NOT use triggers/shoulder buttons for ranged combat mechanics and when that is.
