I have a Glock 20 that has a new Lone Wolf 357 sig barrel. It fired fine first 2 rounds and then seems to tried to go to battery with the 3rd rd and didn't quite make it. It lacks 1/8 to 3/16 inch of being fully closed. I have tried to move slide back by hand but it is stuck pretty tight. What must I do to clear this round?
With the 10mm barrel it ran fine.
