I still stand by my point, in basically all tv shows and movies guys have endless bullets. This show is definitely not unique in this aspect.
You can hope for better, but doesn't seem to happen.
I still love the show, I just am not bothered by the unlimited gun and good aim.
Could it be more realistic? Sure, will it be? Doubt it.
I have a photographic memory, trouble is most times the lens cap is on.
