G35 Gen 4. I've put about 400 rounds through it so far and it is continuing to have a serious problem with feeding. I've swapped out the guide rod and recoil spring set up to 2 different ones and it doesn't matter what, it still fails to feed at least one per mag. These are stock Glock mags. It is hanging up on the left side as it tries to push the shell into the chamber. The new style ejector forces the ammo to come out of the magazine with a slight cant, then it hangs on the left side of the barrel as its trying to go in. I'll upload a couple pics, one of a shell showing how it always sticks and another showing the barrel and you can see by the shiny spot, where the bullet is hanging up. Any help would be appreciated. My first thought is to smooth out this area to let it feed better but I don't want to ruin a barrel.
