A lot of weird choices there but build should be salvagable on easy/normal. If you want to keep using pistols, on next level pick 1 point in Dex, take Bullet Time feat and start putting specialization points in there. You can also take Point Shot and all the critical chance feats you can find. Grenadier would also help you.
Alternatively, you have nice stats for using SMG or AR so you can move into them if that's your thing. AR with Commando feat and Concentrated Power is a beast. But you will have lots of useless feats if you go that route.
Stop investing in melee, Gun-Fu was a mistake. Use those skill points for throwing, stealth, crafting and mercantile.
You are only lvl 15, Black Sea should usually be accessed when you are 20-25. I typically go there after I'm done with University.
