It hasn’t come up much, but there was a vaguelyey similarey car-only incident in 2001 (Isla Vista/UCSB) when someone with recognized-in-advance mental issues murdered 4 with his Saab.

We won’t know anything about the limitations if any that the 10rd magazines imposed. It is pure speculation to suggest they had any affect. It would be somewhat useful to know how many shots he fired before shooting himself, but even that may not be indicative.
Widespread gun ownership in the USA just doesn’t follow the same fact pattern and history of other modern 1st world nations. Also, many of the other countries are hard to compare because they don’t have the same disparity of income, racial/heritage/creed/immigration mixing/lack of homogenaity that the US does.
The largest numbers of deaths are concentrated around poverty ghettos and get discounted by those who live in relative safety outside of them, along with the statistics they generate. Probably similar in other countries like Brazil with favelas. Are the problems highly concentrated or spread and distributed throughout the fabric of the whole? In the USA the drivers of the numbers are highly concentrated, but the mass shootings seems to be spread throughout the whole (though statistically very small in number of deaths).
I think it ultimately comes down to a few core items:
-do you believe law abiding civilians should have unbiased access to guns?
-do you believe is is wrong for the government to confiscate property?
Given the number of guns already owned in the USA the two above issues probably outline the extreme positions and of course there are a broad mixture of compromise options in between.
