Gun Control Reform Activism

PJ: Consider this: the case is heard by SCOTUS and they vote 4-4. The lower court ruling then stands and gun laws change. Interesting.

What do you mean 'gun laws change'? This 9th circuit ruling stated that concealed carry was not a constitutional right, based on heller's '2ndA not absolute'. I don't think that Concealed carry is considered a constitutional right as it is, since there were a dozen state's constitutions which banned or restricted carrying concealed weapons dating back to the early 1800's.
If appealed to the supreme court & a 4 - 4 ruling returned, this fuller 9th circuit ruling would remain, yes? hoping that is what you were saying. Since yes gun laws would change or be clarified, not by legislative action but by judicial action (a better term for it).

Actually, the 9th cc ruling might not 'remain' except on a temporary basis, as the SCOTUS could somehow revisit the case after a full scotus is back. Dunno exactly how that works.
