Are you looking to multiclass Investigator and Gunslinger?
Mysterious stranger is usually not very optimal for android as you get a penalty to charisma.
If you have access to a lot of tech guns, techslinger is quite fun, just pick a good weapon to use your technic training for.
You seem to be missing all ranged weapon feats from your list. If you intend to be any good with a gun you should pick up the basics at least, point blank shot, precise shot, rapid shot, deadly aim etc. Take at least 5 levels of gunslinger to get dex to damage. If that is too much, you could go for trench fighter 3 to get dex to damage.

That's the bounus feats you get for being a investigator I forgot to add the deeds for gunslinger and the other feats I'll get those in a sec

[Cheesy bucket]

So you get feats at every odd level is that total levels or is that by class

Total levels. I'd second leaving Mysterious stranger aside. It isn't as cool as it sounds.
