I understand that we can convert the Shield down, from .40 to 9mm, with only the Barrel & Mags... No Slide required, like with some models... But...
Can we also convert the Shield UP, from 9mm to .40 by buying just a barrel and mags as well? Will the 9mm extractor successfully grab the .40 case?
If so, this is something I might like to try. It would be my 1st .40.

Folks, the cartridge head dimensions on 9mm and .40 S&W are DIFFERENT. Thus, conversion from .40 S&W to 9mm MAY work sometimes, but that is more luck than anything.
.40 S&W to .357 SIG and back works with a barrel and magazine change ONLY because those two rounds have the same head dimensions.
What you are doing may or may not work, and I certainly would not bet my life on it in a self-defense scenario.
Bad idea.
