The biggest problem I see is your feats are all melee-build and your talents are all ranged/firearm. You're gimping yourself because your feats and talents don't align.
Here is what I'd do.
Trade in the bard levels for Gunslinger. You'll get firearms and grit for free, opening up your talents for Sniper's Eye and Snap Shot.
OR
Lose the firearm/grit stuff and build toward spring-attack, lightning stance, and the Scout Archetype.
But really, having two talents tied up in firearms isn't helping you in melee, and spring attack does nothing to help you shoot things.
