What are these machining marks on my Shield?

[Sapperforward]

I've wondered since the day I bought it but never asked. Their are 3 small indentations on the inside of my slide.

Are these for balance purposes? That's my only guess.

From the research I've done it denotes what machine produced the part, or the process used to make it.

It's Braille for 9, as in 9mm.

This is my understanding

Same here

Might be a date code or material batch code.

You seemed to have solved it. Or at least are headed in the right direction.

They went through the same machine that makes domino tiles...there might also be traces of peanuts for those of you with allergies.

Do you have anything useful to add to these threads or just the usual drive-by snarky comment?

Sorry. I should lay off the wine while logged on.

Odd that if it's a note to link to a machine that they wouldn't just engrave a lot code. Simple as ex: AB1, HB78

Great idea.
