FN 5.7

[SilverStacker07]

Is the FN 5.7 legal in California as long as there's a 10 round mag?

THE FOLLOWING MODELS ARE CA LEGAL:
FN 5.7 I.O.M. (Matte Black) / Steel, Polymer Pistol 4.75" 5.7x28mm
FN 5.7 U.S.G. (Matte Black) / Steel, Polymer Pistol 4.75" 5.7x28mm
FN Five-seveN (Flat Dark Earth) / Steel; Polymer Pistol 4.75" 5.7x28mm
FN Five-seveN / Steel; Polymer Pistol 4.75" 5.7x28mm

And these are the current Gen2 5.7 If your FFL doesn't agree find a better FFL.
FN Five-seveN (Flat Dark Earth) / Steel; Polymer Pistol 4.75" 5.7x28mm
FN Five-seveN / Steel; Polymer Pistol 4.75" 5.7x28mm

And these are the current Gen2 5.7 If your FFL doesn't agree find a better FFL.
FN Five-seveN (Flat Dark Earth) / Steel; Polymer Pistol 4.75" 5.7x28mm
FN Five-seveN / Steel; Polymer Pistol 4.75" 5.7x28mm

Why they didn't include the "MK2" nomenclature that FN now uses to designate the Gen2 is beyond me.
