I think that the range on certain gun models should be increased to the same length of a vial (or at least as long as enemies can shoot) with the exception of the polaris (I always thought of it as a shot gun).
Reasons for this: It feel kind of odd that we can through pot and vials about twice as far (if not more) as we can shoot bullets. I know it a game and game dont need to have logic but gun that are that short range just seems weird.
I also think the range of guns should very between the gun. For example polaris should continue have the same rage but guns like antiguas and blitz needle should have longer ranges, and guns with only twp shot magazines (like the callahan) should have the longest range.
This can't be possible. The guns are this range for a reason. If you shot your gun forever into space, all the enemies would die easily. The game is meant to be challenging, not easy and boring.
