Advice playing and making a Gathlain Pistolero Gunslinger / Skinshaper Druid

[DigiOz]

I'm about to start an Iron Gods campaign and I came up with a fun concept A Gathlain Pistolero Gunslinger/Skinshaper Druid.

character concept:

Super quick concept sketch for those that want a how does that work:
My character traveled with the witch market as a hanger-on for many years, nothing ever catching the fancy of his young mind. One day he follows a caravan away from the market, the caravan is attacked and everyone is killed, not that he really cared, but what really caught his eye is the magical hand canon that one of the bandits used. Completely enamored he follows the Bandits deeper into woods, soaking in all the info that he can about this wondrous item. Eventually while they are sleeping he flys in and steals the pistol and it's kit. During this time the Witch Market has moved on, leaving him stranded on Golarion. Not that he cares because these mortals have such wonderful toys! As he starts flittering from town to town, trying to gain knowledge about this magnificent device he spy's the light of Torch in the distance. Like a moth to a flame he makes his way there, where he becomes entranced with technology as well. These humanoids really are wonders of Nature!

Couple of character gen notes: I am going with the Symbiotic Imbalance for average flight instead of poor. Traits are Local Ties and Voices of Solid Things (Witch Market). I am also planning on using a medium sized pistol until I can craft my own, taking the -2 to attack.

What I need advice on is the following:

How would you handle firing while flying? or reloading?

Are there any hidden pitfalls of playing a small character?

What issues can I expect being a Fay? any other weird issues?

I am considering just a 4 or 5 level dip into Skinshaper Druid, how would Alter Self work on a fey creature? Would they still be fey, or would they become the humanoid type?

Any other pitfalls or issue that could come up for me and/or my GM? Thought on a build?

First thing is that I would make sure your GM is cool with a flying ranged character from level 1. They can be kind of disruptive by being able to negate a lot of low level tasks by flying around them can make combat challenging for a GM to balance due to the lack of threats to PCs that can't be reached in melee.

If your GM is cool with it though:
1) There is nothing special about flying and using a gun. You fire and reload just as though you weren't flying.
2) I wouldn't really say there are any hidden pitfalls. Smaller damage dice and a bit easier to get pushed around by melee types, but all that's pretty apparent.
3) As Fey, you aren't affected by spells that specify humanoid. For both good and ill. Shrink person, enlarge person, and charm person all wont work on you.
4) Technically Alter Self would allow you to assume the form of any medium or small humanoid, but do take note that it doesn't change your type from Fey. Basically you would be wearing a really good humanoid costume, but you don't become humanoid.

The GM is onboard, and in IG it is a little less of an issue, I'll be slightly OP in the beginning, but most of the 1st 4 levels in inside a "dungeon". Also gunslingers are not as OP against creatures with Hardness, as Adamantine Bullets get expensive at 7gp per shot, even with the discount.

We were thinking of maybe adding a fly check to firing a gun while flying, and I'm curious if anybody has played with anything like that.
