Switzerland is a good model. The NRA loves to point at rates of Swiss gun ownership. If the USA implemented all of Switzerland’s gun laws I think you’d be okay.
One of the big differences between US gun culture and Swiss gun culture is that in the US we believe in a certain right "to enjoy arms", to keep and bear them in an undisciplined and disorganised way.
But they wouldn't get access to the ammo needed to use those guns, which are stored in a central community location to combat an unwanted suicide problem (and aren't they semi-auto anyways?).
They also aren't bought, but part of ones' militia service. You know, that first clause of the USA's 2nd amendment that the pro gun lobby says to ignore.
Good article on this:

Of course, the text is vague enough that everyone will simply draw out whatever meaning they find reinforces their biases. Given that the most fervent upholders of the amendment today were draft dodgers back in the day, it is safe to say that protection of country is no longer important in their reading of the amendment.
At any rate, even if we accept that the clause is prefatory, that doesn’t make it meaningless, it has an effect on how gun rights should be maintained (so that the populace can overthrow the government or protect against foreign invaders, it is not protected for self defense, sport hunting, target practice, etc...).
There are several things wrong with the above statement ...
First, in many (most) states of the United States, you can indeed purchase a fully automatic weapon / suppressor / grenade launcher / "destructive device" / etc. You'll have to pay a $200 transfer tax, submit to registration and fingerprinting and either get local CLEO signoff (Sheriff, Chief of Police) or purchase as a trust. Interestingly, you also sort of give up your fourth amendment rights as you grant the BATF right to check on the "device" at any time, for any reason.
Second, military (automatic) weapons in Switzerland are distributed by the Swiss Army and are kept in local possession under those auspices. A swiss cannot simply walk into a gun shop and buy an MP5 on a whim - regardless of background check.
Finally, and most importantly, Swiss gun laws were dramatically reworked in the past year as part of a general normalization of Swiss and EU regulations. There was a referendum and it passed - many aspects of Swiss gun laws that you may romanticize are now a thing of the past.
This is being dishonest. Since the registry was closed in '86 there have been no additional automatic weapons added to circulation (for civilian owners) so prices start around $10k. They are basically unobtainable for people who don't have $10k to drop on a hobby and don't want to commit a felony with a coat hanger.
For the sake of argument, however, a brand new rifle chassis mated with an RDIAS seems to fit the bill, yes ?
With the level of saturation, not providing safety education is the most irresponsible course.
