80% lower trigger pin holes.

For anyone who has completed an 80% lower, have you had trouble with the trigger pin holes enlarging? I have an anodized lower coming in and I'm wondering if I should use KNS pins on it to prevent the holes from wearing out since the anodizing will be missing.

Anodizing is just dying the aluminum oxide layer after unnatural formation. Its not very hard. Also the aluminum oxide will naturally form with time

No issues.
