Is the sear solenoid releasing the hammer? Does it click?
When you say breach cycles...you mean, when you pull the trigger?
If not try unscrewing the trigger stop screw so the trigger goes back further and alsothe top set screw....
try resetting to FACTORY settings.
If not...put allen key down through the top of the main body and unwind the hammer lug, till the hammer drops forward, while pulling the trigger
