Edwin, yes but, this would change any FX-9 with less than a 16 inch barrel from a Pistol to an SBR (Short Barreled Rifle) needing NFA Registration and a $200 Tax Stamp. Cheers and stay safe!

Edwin, yes this will fit your fx9 just fine but this is a stock, not a pistol brace. Adding a stock to a pistol reclassifies it as a short barreled rifle and require a $200 tax stamp. You need a pistol brace. Sorry but hope this helps.
