At the base of all the pins (hammer, trigger, etc) there seems to be a raised boss.

I usually debur/square up the base , polish, and shim but I've not seen the raised bosses at the base before.... That I can remember

Are these ok to debur and polish flat?

I wasn't sure if maybe because it's an aluminum airweight the pins may have raised bosses for added support or for another reason Im not aware of.
