Really, And where have you provided the proof for your assertions? I don't see any in your posts at least.

The above data is a bit dated and data for some countries is missing, but I don't think the there would be any deviation in the overall trends.
As per the data listed above, US ranks number 1 in gun ownership with an average of 88 guns/100 people, Yet, countries with ownerships ranks that are way down in the list at rank 74 (8.1 guns /100 people), rank 88 ( 6.2 guns/100), rank 92 (5.8 guns/100) are at the top in fatalities. In fact, as per the list, US ranks 28 in that aspect.
BTW, India is not that far off in ownership rank from the countries with high gun fatalities and Pak is much higher ranked, unfortunately, fatalty data for Pak is not provided in the list.
