The only thing in my safe I haven't shot is a vet bringback, matching 1937 J.P. Sauer and Sohn K98 Mauser and it's day is coming. I've shot my matching, except for magazines, 1916 DWM Luger but not in 40 years and it's day is coming again too. Last I just bought a matching 1924 Carl Gustoff M96 Swedish Mauser and since only 2149 were made that year it too is reserved for the proper time. Of course I had to shoot it when I got it.
Guns were meant to be shot but some are reserved for special occasions.
