When using Federal Hydra-Shok or Remington Golden Saber ammunition, my Para Companion C7.45 will not feed from a slide lock release. The shell drives straight ahead into the feed ramp. I then have to push the shell back toward the rear of the pistol (back into the magazine) in order to allow the magazine to release. The gun does this with both the factory magazine and a new Chip McCormick replacement magazine. The gun does not jam, however, when I rack the slide to chamber a round. Also, ball ammo doesn’t jam the gun (either from slide lock reload or loading by racking the slide). I wrote Para Ord, and they said this is normal behavior, but I don't agree. Any ideas on how to fix this?
