Actually, that's NOT Normal.
The connectors job is to always pull the triggerbar downward.
That is why it's tab is angled downward. Otherwise the cruxiform will not disengage with the firing pin lug.
Hmm. I didn't really look at that pic. You sir are correct. That is not normal. I just took mine apart and the only way to get it to do that is if you bent the connector while polishing or damaged the trigger block.
If it were my gun I would buy a new trigger with bar, original connector and new block for the trigger housing and start over and NOT do the polish job.
The trigger willmwearnin by itself with use. If the gun will have a maximum of 5000 trigger pulls over the next few generations of your family then this fluffing and buffing will be fine. If you shoot it enough which also gets you familiar with the piece it will be worn in on the surfaces that only need the wearing in.
Nice catch there. I didn't really look at the pic. I have seen people bend connectors to lighten the pull and the result was a full auto part. At that point it becomes regulated under NFA. And you manufactured a full auto part. Not good if a police officer is at the range when you glock goes full auto on you.
Replace the parts to be on the safe side and let it wear in on it's own.....
