erm... reduce the number of traumatic, life-threatening situations by taking away the guns? Get your police force under control and stop trying to control peoples minds and bodies could be a good start?
I am fairly skeptical of the claim that banning guns would significantly reduce gun violence. People who commit the most gun violence crimes (criminals) will find a way to get guns regardless of the laws. I live in a country where it's very hard to get weapons legally, yet almost every drug bust in the news also contains a significant amount of confiscated firearms.
You say that drugs busts etc. outside the US will often have guns involved. Yes, criminals can still find ways to get them but ordinary people won't be bothered with this.
The Netherlands for example has Europe's biggest port in Rotterdam and sees an incredible amount of drug-related smuggling. It has 3.9 guns per 100,000 people (107th in the world) while the US has 88.8 (1st in the world).
The rate of murder is 73 times more than the Netherlands.

Look at the murder rate: https://www.nationmaster.com/country-info/stats/Crime/Violen...
See how high the US then see how far you have to scroll down before you start seeing European countries appearing there.
