Are u enjoying ur pirates?

Afff I just hope ther range on Double Fire goes up over time or something because it is just wayyy too short as it is now.

Anyone know what factors attribute to gun attack range?

It does. It's based on the level of the skill, and goes up by 15 every two levels. At max level you can shoot almost as far as a sin. I dunno if the normal attack range ever goes up. I'm hoping mastery affects it, but I dunno. Half of your skills increase in range over time; it's an interesting mechanic.
