Not the best picture, sorry.

I've got this American Arms (Zabala) 10 gauge SxS and it needs a little work. Can anyone recommend a good gunsmith that might be up to the task? Parts aren't common for these so depending on what she needs parts might have to be made from scratch.
It locks up great but sometimes has a hiccup opening all the way. Theres a pin not seated properly. And one of the firing pin retainers is not sitting flush or plumb. Not sure what else might need attention.
I've also got a second set of barrels that fit but not quite perfect. I'd like those to fit up better and then probably chopped down to 19 inches.
