I just bought a new springfield XD-40 caliber, Mine is the 4" service model and I was wandering how you guys that have them like them and how well do they shoot for you. What factory ammo seems to shoot the best in this gun? I haven't shot mine yet but here are some of the loads I had my dealer order me: Remington 165 grain golden saber, Speer Gold Dot Personal Protection in 155 and 165 grain. Also has anyone tried the corbon jacketed hollow points in the 135 grain load? I have never owned a .40 caliber before so I'm not really sure what grain bullet this caliber seems to shoot the best but from looking at the ballistics from all the manufacturers the 180 grain loads seem to have the least energy. Thanks.
