I've been trying some 9mm reloaded lead round nose in a G19 w/a Lone Wolf barrel. I've put just over 190 rounds through it without a problem. On the last magazine she jammed after five shots. The slide has almost retuned to battery and is now immovable. The barrel is slightly angled. There is a live round in the pistol. Nothing concerning an immovable slide turned up on the search. Any suggestions?
