I disagree, they would do a lot of good if part of any weapons being available (not just guns, but FPV drones and ammo for them, anti-tank and anti-air missiles, small mortars, and so on), but not for crime levels. The benefit would be in improving political stability (no, it wouldn’t help MAGA and such, because they don’t really want a violent takeover, they want an administrative takeover and then unpunished violence against those who can’t defend themselves).
When only rifles are available, it doesn’t help that end at all - you can’t fight the government or the invading army or some terrorists with just rifles.
So I agree that one has to pick a lane here. If we understand private weapons’ ownership as that well-organized militia to protect against tyranny yadda-yadda, then that includes a lot of stuff. Drones with grenades at least. If we don’t and, say, the national guard is that militia, then allowing just pistols and rifles lacks the advantages, preserving the harm.
