I have a new saint victor pistol. I have not fired it yet. I have run some dummy rounds to get used to the function of the gun. After I load a round and go to eject it by pulling the charging handle the handle will not pull back. It seems to be stuck. It only does this when a round is chambered.I have to use a screwdriver to dislodge the carrier and after moving it about 1/4 inch it will pull back the rest of the way and eject the round.It only sticks when a round is chambered.When the chamber is empty I can pull the charging handle with no problem. Any ideas or help would be appreciated.
