The politics landscape has changed quite a lot. What changed is that gun companies lobbies lobbied the government and bought a bunch of politicians on both sides of the aisle and they continue to lobby to this day.

They also made a big push to convince the general population that guns are necessary for home defense, hunting, personal defense/security, and other recreation. And played up those factors to the part of the population that wants to gravy seal it up.

Further, there's an increasing lack of bipartisan support for most legislation (not just gun law). A lot has changed.

In order to change an amendment you need to take a couple of steps.

One of these is getting either a 2/3 of states to call for a constitutional convention or for 2/3 of both and Senate to agree to ratify the amendment. So I think if you look at the political landscape of today you can certainly understand why it hasn't happened.

Damn straight, there are so many laws stating which weapons/accessories are legal AND it does not violate the 2nd amendment, nor does it require a constitutional change.

Example: Federal Assault Weapons Ban https://en.wikipedia.org/wiki/Federal_Assault_Weapons_Ban

The 10-year ban was passed by the U.S. Congress on August 25, 1994, and was signed into law by President Bill Clinton on September 13, 1994.[1] The ban applied only to weapons manufactured after the date of the ban's enactment. It expired on September 13, 2004, following its sunset provision. Several constitutional challenges were filed against provisions of the ban, but all were rejected by the courts. There have been multiple attempts to renew the ban, but none have succeeded.

I find myself arguing with my coworkers about this all the time, but I like to sum it up like this.

If there are arms you cannot bare, then the second amendment is not limitless.
