Congratulatons your acquisition, I would leave it as is, enjoy shooting it and clean it properly every time you've been to the range. Be careful though it's an old gun so avoid high speed and high power ammunition!
Safe shooting.

Sergio,
You always caution new guys about avoiding "high speed and high power ammunition", but you do not tell them what it is or what to use.

In my experience lugers require "normal" ammo and none of it is called either high speed or high power in the US.

We do have "+ P" and "+P+" marked ammunition - which is to be avoided in a luger. Also the "Nato" rounds are hot, they have the cross in the circle, so should not be used.

Is this what you mean?
