Markings on the frame...new to this

[thestaleness]

I just bought my first p64, and after getting everything fixed up the way I want it, Ill be buying another for sure.

My question is this...
Does every p64 have a bunch of random markings on the gun. For instance, on the left hand side of the frame is a set of 3 connecting triangles barely etched into the side. I also have a few markings on the trigger guard and the same ones are in the groove on the back sight. A friend of mine told me that they are probably factory markings but I was curious if anyone knew what they meant.

This is actually my first pistol as well, I posted some questions in the modifications thread too if anyone can help with those.

Thanks.

Welcome to the world of surplus pistols. I think every time someone picked a gun up they had to stamp something somewhere. All of my surplus guns have stuff stamped all over the place.
