Actually, the side plate would be the first area to crack as it is held in place with 3 screws to a precise fit. Because of the high pressure on the frame by the magnum cartridge, it will affect those areas fastened to the frame first such as the side plate and even wooden grips (if you have them, I would use rubber for magnums myself).
Shattered the internal plastic structure of the rubber grips already (pics a few pages back) and might tig weld the side plate instead of replacing it as a big "up yours" to S&W.
The epoxy set up nicely for the front sight and will get tested in a couple of hours.
