I'm not arguing at all. I just want everyone to be on the same page, be comfortable with the ruling, and put this to bed.
This is from Amidon:
After discussion with the USPSA President on this issue, it was determined that there is no difference, really. Caliber could be interpreted as the width of the bullet, more so than the actual round.
This would allow the Tanfoglio Stock III to have a slide that states 38 and a barrel of 9mm. As the rules state caliber/cartridge .38
cal./9X19 .0354.
