What difficulty are you guys playing on?
I never ran fully out of ammo, I only ran out on one or low on both in long fights with lots of enemies. Found plenty of ammo everywhere outside of battle, only bought ammo once after Mrs Ghostface.
That said though, my primary weapon is the carbine and its easy to one shot most enemies... So maybe I just picked the least ammo intensive weapon.
