Brass deformation
 

I just got my Luger, sorry if this is already posted or common knowledge.

When i fired it i shot it around 32 rounds and i noticed all the brass was flat on one side with a bit of brass even shaved on some. Mine is a 1936 standard military Luger by mauser. If you cannot tell I am still pretty ignorant on these guns. Just looking to learn what i can.

Pretty normal, they bounce against the receiver on their way out.

Two of mine do the very same thing.....normal.
