I agree with rifleshooter474. I a big guy and most of the time concealing the XD-.45 is not a big issue. However, sometimes something a little smaller would be nice. Also, the versatility would be a good advantage if getting ammo ever gets to be a problem such as after the last POTUS Inaugeration. I also like the idea of having more than one firearm that has the same operating drill/controls.....any of those trained on them (wife, sons, etc)could pick them up and shoot.
