Trigger screw hole defect?

[River Jordan]

I have noticed that every third generation Colt that I have ever taken apart has the same little problem regarding the trigger screw hole.

The slot for the hand always intersects the screw hole leaving a bit of a hole in the thread area. This leaves the trigger screw slightly unsupported in effect although I don't think it matters.

I have a 1977 third gen that has this problem but it doesn't affect it to my knowledge.

Is this common on 1st and 2nd gen guns?

is everyone now taking a screwdriver to their Colt to see what I am talking about?
OR is this something that no one but  me has seen?

It's very common and absolutely nothing to worry about.
