You mean FNH.
The FN FiveseveN (their spelling, not mine) is known to have issues with firing out of battery. And the 5.7mm ammo turns out to be nothing spectacular in civvie-legal loadings.
Look into a Springfield XD45.
I’m not a fanatic gun guy but I have what I have from a buying spree from before the last ban. Chinese stuff and Colt AR. I find the cheap 7.62 stuff to be more accurate and the 223 stuff to be a lot more expensive. P226 9mm works like a charm. I was just thinking it would be interesting to have the FiveseveN but is it practical? Very few sell it in gun stores but it is on the internet. It is not widely accepted by law enforcement or military as far as I can tell. I’ll talk to my friends that know about this stuff. I’m more of a Camera guy but when I start hearing ban language I get cautious of my future.
