If Daryl's single edge razor does not do the trick

Close the gun completely.

Place a soft pad on the action.

While holding the gun muzzle UP
Use a soft wooden rod (pine) to gently vibrate ( light taps) the action,
tapping the soft pad.

This should allow the firing pins to move back into retraced position.

Gently try to open the action

Mike
