I got one, local guy has no clue. He did a top latch return spring but can't return trigger to prior single trigger, mechanincal status. Any idea who may be able to deal with this?

I can't log in except via my old iPad. My email is eepink@icloud .com. Prefer to deal that way as this website prohibits my use of my new iPad Pro. G'rrr.

Help!!!
