The piece I am working on now contains some heavy gun battles, the main characters do not normally carry weapons of their own. Instead they pick up guns as they go through the different settings using whatever they have available at the time. I'd like for one of the two to grow an attachment to one of the guns they find and carry it for the remainder of the story. My question is, should I make mention of the need to reload the various guns they use if the gun I want to become a permanent fixture for the rest of the story would run out of ammo some time after the next gun battle?
Secondly, i'd like there to be a scene where the favorite gun actually does run out of ammunition at a costly moment. This could effect the answer to the original question.
