MAC i also bought the XDS, and yes its a beautiful gun to shoot regular WWB 230gr ammo. i shot it with Federal HST 230 +P. and all i can say is that gun hurt my hand so bad it was shooting a lightweight 357 mag revolver.. ouch ..
shot my friends fullsize XD45, and it was alot easier on the hands. i can only think the XDM 3.8 will be in the middle with +P defensive rounds
ended up selling the XDS in favor of a soon to be owned shield 9mm.
