would a gun be able to benefit from the effect of 'gravity bow' (or it's identical counterpart 'gravity gun')? A gunslinger could spend 4k for an item granting continuous 'gravity bow' (spell level 1 x cl 1 x(2000x2)). using this setup, my 9th level gunslinger with a musket is now hitting for 5d6+x (3d6 bullet, d6 acid, d6 electrical) per shot.
