Lugers are a lot of fun.
Give them decently-fitted magazines and good solid loads and they will chug just about forever.
Yup. you really need to provide more inromation. There are all kinds out there, including some stuff coming out of Russia that is beat to death and almost worn out. There are also brand-new 90-year-old works of Luger art still to be found..... bringbacks from the time of the Great War or Hitler's War, carefully looked after for 60 to 90 years........
Some photos would be good.
Also, check the condition of the bore.
SO much depends on condition.
