Just bought the PT111 today, got a great price on it, was looking forward to using it Saturday to qualify for my carry permit. I already have a Gen1, and from looking at the pistol and the manual that comes with it, it seems to break down the same way, with one exception:"5. Carefully release the slide catch, letting the slide go forward, then pull the trigger and pull the slide off the frame."That bit about pulling the trigger was new, but oh well. So I did it...and now the slide is locked onto the frame, and the trigger is locked back. Neither will budge a millimeter. What in the world did I do? And how do I undo it?
