I've heard about a lot of guys doing that. It is something to consider but it's not something I "need" to shoot. I have other 9mm's I can shoot that are just as fun and nothing to worry about breakage. I suspect it will just be something to take out occasionally with the kids and grandkids so they can say they've fired one.
I'm not that hung up on the P38, the Luger is my iconic Germanhandgun and I'm not afraid to shoot that one.
