So why is there no black market gun manufacturing industry in any other country that has strict gun laws?
Is this based on research? I think you are reaching into the clouds again.
For example, I am using drugs as info is easier to find.

Iran is one of the most active executioners of drug offenders. Under the Islamic regime, up to 500 drug traffickers are executed every year. More than 10,000 narcotics traffickers and drug users have already been put to death in Iran in the past few decades. Drug possession and use is also punished severely. Getting caught with a few grams of marijuana could get one up to 70 lashes.
Wow, I was totally confused what drugs and Iran have to do with this but I think I get the point that you're trying to make. That combating drug trade even with the harshest laws still doesn't get rid of the problem.
Well here's a couple things about that situation:
1. They're right next door the opium/hash manufacturer of the world. If this was a methamphetamine problem then I could understand but these are imported drugs. Unless Iran invades Afghanistan, they can't really do anything to stop the problem at it's source.
2. The Iranian legal system is a corrupt pile of shit that makes no sense. There's a million examples but one that my father (who's Iranian) told me was about this one DA or judge or something that made it so that anybody caught with more than a few grams of heroin will be automatically put to death. Quick trial, no appeals, no mercy. In 6 months, this drove up the price of heroin by 5 times until a son of somebody important in the government got caught and was being put through this death sentence express lane. This caused investigation of these trials and they found that a lot of the people being put to death had a 30 minute trial and just totally circumstantial evidence. This caused them to scale back the punishments to whatever they were before.
So what I'm saying is that even if Iran was a similar situation as far as importing of illegal goods, do not ever put faith in the Iranian law enforcement/judicial system.
