One of the more prominent differences between 2nd and 3rd generation guns is that 2nd generation guns have straight barrels and 3rd generation guns have barrels with a smaller "waist" near the end.
This is closely related to one of the other prominent differences: most 2nd-gen guns (the 645 and 745 excepted) have a M1911-style removable barrel bushing. The M645, M745, and the 3rd-gen pistols have fixed bushings.
