I still think that any 90 yr old collector piece is best not to shoot - if it is mismatched, reblued or the like, then that is another matter (I shot a 1913 luger framed mismatch yesterday)
NOTE: I have blown out a breachblock by using +p - it is not recommended by me, but that is because of personal experience. Rather than more oomph, I suggest something like the super expanding cartridges

Or take a 45 or 44 mag for a feral hog
If it is a 1904, then it is worth tens of thousands of dollars, in ANY shape....
