Our government is not yet strong enough to take all our guns. Hell it's not strong enough to make us all pay taxes. But they could erode things litlle by little. And that's what is ahppening.
After pistols are limited to 6 in the mag, they'll strenghthen the "loophole' of preban stuff. Pay the gun companies to reeplace the old mags, decide that mags more than 10 years old are probably unsafe because of the spring, etc. Later when 6 shots are standard, start to retire semiautos because revolvers are just as good but can't be reloades as quickly for mass shootings.
To ban guns they've got to somehow get rid of semiauts, in rifles and shotguns. Fortunately those are now the most popluar guns, in the USA. We've gopt to keep it that way. Most people in the world can't have semiauto guns, eventually, we'll be isolated. America won't support giving up guns, but the world as a whole will support it.
