Don't worry about hanging on to big guns only for boss fights, every single one has either guns in the same room you fight them in or right before you start the cut scene.

Though if I had to pick one the Heavy Rifle has been particularly helpful.

Dunno, I've never used iron sights after I got the laser pointer.
