I bought a brand new Springfield XD-9mm 3" yesterday. Took it to the range and ran 200 rounds through it. All ammo was factory ammo, 124 grain Winchester standard pressure. Tonight I was cleaning the gun and noticed that the outside of the muzzle appears to have a "bulge". It's so slight that I can't really get a photgraph of it but I can certainly feel it when I run my had over it. Imagine the muzzle to about 1/2 inch from the muzzle feels just a bit thicker than the rest of the barell. There is surface wear around the barrel at the point where the bulge begins. The inside does not look any different though it does look like there's some unever wear at the crown of the muzzle. Although the barell may have looked like this when I bought it, I doubt it. I cleaned and lubed the gun before takinging it to the range and assume I would have noticed this. I'm pretty careful about checking out a gun before buying it and/or shooting it. What the heck could have happened? The gun seemed to function flawlessly and was dead-on accurate.
