I've taken apart every S&W I've owned. I do a little polishing if it looks like some is rubbing more than it should or where it shouldn't. I've taken apart a Colt SA to replace broken springs. It's not that tough to take one apart. I did have trouble with a SA but only one time on one gun.
I think given the current situation in the world that knowing how to do a few light repairs is a good skill to have.
