xd 9mm mod2 4"

Any barrel mods out there for the Mod.2 service model other than the storm lake 34107 barrel? I received Stormlakes barrel yesterday and well the outcome..the slide is pushing forward a little. Only bought it because someone from SL said it would fit perfectly..

Ok, first off let me just say that my OCD is bad. So, that's why I'm posting. I'm looking for a rail mount light for my XD 9mm Mod 2 4" Service Model but I want something that will be flush with the barrel of the weapon. I've been searching and searching and can't really find anything that...
