My XD .40 has the 4 inch barrel, easier for concealed carry than the 5 in barrel. To make things better for home defense at night, I recently added the "glow in the dark" sights for limited visibility. Had to go to a local gunsmith to have them put on, but knowing for certain where your barrel is pointed makes all the difference in the world.
I've fired in excess of 500 rounds through mine without so much as a single hiccup. A (now retired) police officer friend recommended the XD and it's what I carry whenever leaving the house.
