A vote for either the Bersa Thunder Nine or the Bersa Firestorm 9mm.
I favor the Firestorm platform. The safety functions as a decocker, and you can then flick it back down(off) for carry. The DA/SA trigger is quite managable, and the ergonomics are, IMO, very good. It has everything you are looking for:
Accurate Check
Reliable Check
9mm Check
Ambi safety Check
Ambi mag release Check, if reversable counts
No magazine safety Check
Drop free magazine Check
Hi-cap magazines that are reliable and affordable Check. 17 rounds enough?
DA/SA Check
Under $600 Check
Also, although not mentioned - good customer service Check
- warranty honored Check
stay safe.
