The picture below is not entirely clear, but it appears your far left sideplate screw is a buttonhead indicating the original grips would have been standard service grips which left this screw exposed...The use of Magnas or target grips of any kind would have caused the upper corner of the right grip panel to protrude slightly and possibly weaken the grip material...This can be remedied by either machining a small indention with a drillpoint in the grip where the screwhead makes contact, or just replacing the screw with a flathead design...  ...Ben

It does in fact warp out right in that spot, and I was not exactly sure why, and it's now funny to me how obvious the reason is. I will go ahead and fix that. I will also check out that link you shared and read up on the case hardening, thank you!
