I am wondering if my XD-40 has an ammo feeding problem. When I rack the slide it feels like there is a rough spot around the loading ramp. It feels like the tip of the bullet is catching somewhere on the loading ramp. I have only fired 350 rounds through my XD. On the other hand my friends Glock 22 and his Sig don't seem to have a rough spot. Could there be a potential problem here or do I need to go and break it in more. I appreciate any advice you guys could offer.
