My P210A came with what appear to be solid aluminum extended floor plates.

I just bought two more mags from TGS (thanks!) and they have hollowed out metal floor plates (might be steel).

Is there any way to get the an extra set of floor plates of either kind so all mags are the same? Yeah, small issue, but on a $1500 pistol...

I suspect that's the way it will eventually be for all the mags that come with the gun. The last time I bought those mags from TGS, they were a mix of floor plates, aluminum and hollowed out plastic.

I got the same from TGS. I would just let it slide . The mags work.

I don't know. My P210A floorplates were both hollowed out steel, but I realize any I might buy in future could be aluminum or plastic. I have other magazines with the flat steel,Swiss type, floor plates and with the steel Legend type floor plates. I'm just not going to worry about it.........ymmv
