Hey guys love the forum, very informative so far. I pick up my first pistol Friday, an XD 4" .40cal. I do not know what kind of ammo to start off with to just get a feel for the weapon and test its functionality. I know each gun has likes and dislikes for ammo but what would be a good one to start with for practice before I go about choosing a defensive round? Any help you guys can provide would be greatly appreciated. Thanks.
