My new HH Heiser holster, home with my 1920's 6" shooter luger in 7.65 cal.
I have the gun's original grips (numbered) but use the Italian-made "swiss" grips from the 1960-70's for range use. I stained the grips and applied a spray-on urethane finish.
I also have the gun's "gemany" stamped magazine, but use a spare M1929 Swiss Bern magazine for shooting :
