I got a new modern (at the time) fireplace for my 30 birthday, quickly to be replaced with a type that is actually providing some heat.. anyway, point is, you did well receiving a Luger!
Also.. to be honest, I think Luger can handle more than we give them credit for. They are old.. and they do not like hot ammunition. But they are not made of porcelain example. An excample to this is one of my previous shooters.. Started it's life in the hands of the wehrmacht, shooting corrosive ammunition with iron covered bullets. Then into the the norwegian army, beeing feed with hot MP-ammo. Sold to an officer using what he had available for free, plenty of hot NATO ammunition. Sold again to another officer doing the same.. before it ended up in my hands. The only non-matching part was the sideplate. The Luger was worn on the surface, but still going strong as I sold it to a home guard officer, most likely feeding it with NATO ammunition even today (agains my advice..)
Why I'm telling this.. no idea.. it is without doubt silly to shoot hot ammunition in an old Luger, some NATO boxes are even marked "not for P08/P38". I beleve in seeing things from both sides..
Welcome btw
