Welcome to the Lugerforum Walter.
My advice... Keep it clean... Keep the moving parts Lubricated (with Breakfree). Keep it in a low humidity place... and SHOOT IT LESS...
If it is really a fine matching Luger... why take more chance than you have to. Get yourself a mismatched "shooter" to put all those rounds through and preserve your current Luger.
Even if one small piece breaks... you will almost cut the value in half when you replace it.
The choice is up to you... The most likely pieces to break? The extractor, ejector and firing pin... If you must shoot it, get replacements now and install them before your shooting sessions.
