Have a 63, the ss version. Tends to gall. Stick with carbon steel blue.
Huh? When they first came out with stainless semi-autos, there were some issues of galling at the sliding interface of the slide/frame. But they soon figured it out and mitigated the problem by proper material selection (while still using stainless steels.) I haven't heard about the issue in a long time.
I never heard of any galling issues with stainless revolvers. What tends to gall on your M63?
