Help!!! Need to Choose a New/Starter Handgun

[Wendell]

Can you please describe in what scenario do you see yourself doing this in this country? Like you're going to the community pool wearing an IWB holster and someone decides to attack you while you're coming out of the water?

The OP asking about handguns and provided a short list; I'd said that - out of his short list - the FNS9 is the only one (from his list) that I'd choose; (YouTuber) 'J Helmsing' has posted excellent, well-considered, videos on many duty pistols, including the FNS and the 509, and anyone considering either the FNS or the 509 should watch J Helmsing's videos on both before making any other move.
