Owners of the FG-9 often comment on the walnut stock as the standout visual element, giving the carbine a look that differs from the typical polymer or synthetic PCC on the market. The combination of wood furniture with a modern aluminum receiver draws both praise and occasional skepticism about long-term durability.

At the range, the 9mm chambering in a 16-inch barrel is noted as mild on recoil and easy to run for extended sessions. The threaded barrel is appreciated by owners who run suppressors or muzzle devices, though some note the threading pitch should be confirmed before purchasing an accessory.

Glock magazine compatibility is the feature that pushes many buyers toward the FG-9. The convenience of sharing magazines with a sidearm is a practical selling point. A recurring complaint is that aftermarket support and parts availability lag behind more established PCC platforms, which is a consideration for buyers who plan to modify the carbine.
