The 357sig propensity for bullet setback could be more problematic than a straight wall case when rechambering rounds.
The Secret Service's findings were the result of objective
testing which included extensive testing with hard barriers. I was asked why I re-barreled my .40 S&Ws to .357 SIG and provided the answer. I certainly wasn't trying to influence anyone in their personal defense cartridge selection - if you think .40 S&W or even .25 ACP serves you better, that's what I'd use.
