Figures. i've been wanting some finger rest ext floorplates, this would have been a perfect deal. anybody know for 100% sure they're different? 45's are metal mags and 40's are plastic but both floorplates fit into the grip the same. I'd be willing to send u 1 to see if it'll work if we don't get a definite go/no go.
Well, I did find out that they are not interchangeable. The .45 plate fits just fine on my plastic .40 mag, but the .40 plate won't quite fit on the metal .45 mag. The problem is the mag material thickness. Oh well, we tried.
