Best I can tell, violent crime has an extremely high correlation with poverty and/or corruption, and little to no correlation with gun restrictions. The presence of extreme outliers is telling. For example, Iceland, Switzerland, Austria, and Norway have high gun ownership rates and relatively relaxed gun regulation, but low violent crime. Venezuela, Mexico, China, and Vietnam have strong firearms restrictions and terrible violent crime rates.
While you're probably right that poverty is part of the problem, counting raw number of firearms is misleading.
Norway is mostly hunting rifles for example. Very few handguns.
Policing is also different. Police is usually not carrying guns, but the moment a gun is reported it causes a massive response. As a criminal, bringing a gun massively increases your risk, as without one you're unlikely to run into anyone with a lethal weapon. It also causes a risk of a far longer sentence.

That's exactly the same in the US, btw. Bringing a gun causes the tactical team to come in rather than the normal cops, and it aggravates the criminal's sentence.

Missing the point, which is that this is a meaningful escalation in Norway where regular cops do not carry guns in most instances. It's a far less meaningful escalation when you're facing armed police either way.
The point both with that and the sentencing is that it creates a sharp escalation from a low risk base.
Escalation only works as a deterrence from negative behaviours if the lowest risk alternative is actually seen as low risk.
Very few countries can compete with the US on the ease with which one can buy a firearm, so if that is your standard, sure. But compared to most of the world, that process is pretty damn relaxed, and gun ownership rates are pretty high as a result. And in some selected ways, those countries are even more relaxed: silencers can be purchased over the counter without a permit, and there is no regulatory distinction between short barrel and long barrel rifles. And in some (albeit regulated) cases even modern full-auto rifles can be owned, which isn't even possible in the US...where the newest full auto gun that a civilian can buy was made in 1986 and likely costs >$25k.
