I have two XDm's... one with SS and one with Tungsten, you will gain some reduction in felt recoil with the tungsten, but none with the SS. I like the SS simply for the looks and the soild construction. The legal production weight for your XD is 32oz with an empty mag inserted, I think the factor weight is listed at 30oz... but not sure if that is factored with the empty mag. Best bet toss it on a scale ansd see if it will make weight!
