Yes. Those are the coupler shoes and they are supposed to be in the coupler body FULLY. That's dangerous. You really should pay more attention. No offense.
No offense taken but the coupler has looked like that since I have owned it for almost 3 years. Not saying that is right just how it has been. I will work on trying to get those shoes all the way in the coupler body.
Per your roll pin comment, all the holes line up there just isn't anything that sticks in the middle of it. I will also look for something to put in there to hold it all in place.
