Glock shooting low and maybe a bit left after night sight installation

[Certaindeaf]

The OPs Glock is fine.

Except that it's keyholing. Something is fundamentally wrong, not fine.

Hopefully it's his ammo that is causing the keyholing.
Not enough information to help with that.

On the POA/POI issue, it appears that the OP has Combat Hold sights, and wants Center Hold sights.
All necessary information to fix the sights is in this thread.

The keyholing is another issue.
Need more info.

I was wondering where you were coming from, thought it was sarcasm at first.
Went back and looked at his target... I only see one oblong hole. Cant tell if thats two shots or a keyhole?

Looks like a keyhole. If there's one they are all very unstable.
