You are right. I rechecked Hong Lu's uptie and the Fullstop Pages. It isn't ''armor'' but steel:
>Tamaki’s Page: “No gun should possess the firepower to penetrate steel or building walls”
The Church of gears wore steel armor in Hong Lu's uptie. This is why he had to circumvent the rule:
>A sturdy breastplate made of steel.
>Some would purchase impact rounds to destroy the metal without penetrating it…
>Some would purchase micro bullets to shoot through any visible holes in the armor…
>… but the child sought a much simpler approach.
>There was nothing stopping him from cutting through metal with his dagger, after all.
>The Workshop-made dagger in the child's hand cut through the worshipper's armor like a knife through butter, and…
>… he aimed the barrel into this newly created gap in the worshipper's armor.
So he opens up the armor outright first and then shoots the gap so the rule isn't broken
