"I don't think lumping in suicides with violent acts is correct."
Okay.
Let's discuss suicides separately.
Let me try to show you the impact of the Second Amendment just by looking at suicide.
Men who own handguns are eight times more likely to die of gun suicides than men who don't own handguns, and women who own handguns are 35 times more likely than women who don't.

Gun suicide rates in the United States are significantly higher compared to the rest of the world. This study found that Greenland is #1, but that's only 56,000 people, so can really be thought of an an outlier compared to the Untied States, which is ranked #2 in the world for gun suicides. You have to go down to Finland, notorious for suicide, to get to a modern country on the list and they're at 1/3 the US rate:
A total of 52,694 (45,110 male and 7584 female) deaths of suicide by firearm were reported worldwide in 2019. The global ASR of suicide by firearm was six-fold higher in males than in females (1.15 per 100,000 and 0.19 per 100,000, respectively), and varied greatly across countries: the highest rates were in Greenland (24.52 per 100,000 and 2.69 per 100,000, respectively) and the United States of America (10.13 per 100,000 and 1.66 per 100,000, respectively), while the lowest rates (0.05 per 100,000 or less) were observed in China, Japan and Singapore.
