And I agree with you on that point. For me given that a handgun is a last line of defense and is more of a desperate measure I would prefer a larger caliber, as if I need as many as 15 rds in a handgun I need to reload my rifle instead. For that purpose I would prefer the 45 but I don't see NATO going to this. The 45 is more of an American phenomenon. I think we're at the point where we might ignore NATO and adopt a 45 for just the US, but NATO as a whole wouldn't change calibers.
