I have a Beretta 92 FS in stainless. If you turn the gun upside down, on the bottom of the slide on the flat edge just back of the nose taper beside the frame extension are three evenly spaced little dimples. They look as if they are 'original' and were milled/drilled not punched as there is no metal raised around the edges. Any idea what they might be for? Only thing I can think of is places where the slide was tested for hardness but they do not look like similar spots I have seen on knives, etc. where that was done. Thanks. Guess I'm thinking too much, huh?

Could be production tracking info. It is common to mark parts with patterns that will tell what shift, machine ETC. I don't know if Beretta does it or not though.

i just pulled out my blued 96 to check the slide and it has ... a "4" roll marked there. it is not related/consistent to the seriel number

marks left from the hardness testing, perhaps...

The mark you describe is typical of the mark left by their hardness testing machine...

Try asking the folks over at the Beretta forum at www.berettaforum.net

They should be able to give you all kinds of helpful info regarding the Beretta guns. :D

Smurf is correct . Hardness test
