I have a few different FNS pistols and interchange some parts on them. Does anyone know what parts are interchangeable on FNS pistols?
As far as I know:
FNS-40 slide works on a FNS-9 frame. I do this.
FNS-9L slide fits on normal FNS-9 frame.
I saw a guy online who attached his FNS-9L slide to his FNS-9C frame and claimed to have fired it. I don't yet have the courage to try this. Any ideas about this?
Also, does anyone know if the FNS-9L barrel will work in the FNS-9 4"? It seems to fit in mine, but I haven't test fired it yet.
I can say that FNS-40/FNS-9 mags will fit in all of the FNS pistols and work if you have the correct slide.
One tip I have: 509 tactical magazine baseplates fit on FNS mags. I put one on my FNS-9c carry mag and it is the most comfortable and concealable mag I have now. Also, the 24-rd 509 mags work in the FNS-9 and FNS-9C.
