Ok. So you are dealing with the player not the character. If a player is a dickhead, no matter what they use; magic, guns, or galaxies they will be a dickhead getting in the perfect hit, the never miss and the always on target shots. If you are fighting T1 there really is no inherent problems with gunfighters.

This does tend to be the biggest problem with fighters. Marksmanship is probably the one area where I would generally recommend a dice system of some form. 

I try and miss about one in every three of my shots, carrying over into other fights, just to keep things realistic for my own benefit.
