An all-out Feinstein gun ban probably isn’t on the way soon (a string of shootings could change that), but its remains the goal of the Dems long-term. They will use the press to wage a propaganda war to alter public opinion enough to avoid a repeat of the 1996 elections. In the mean time, “The Democrats cannot be trusted with our freedoms, and they will politicize every tragedy to accomplish their ends.”
If a gun ban were put in place that greatly restricted some of the most popular semi-automatic rifles and pistols available today, there would be other affects down the road depending on the details. Here we’ll assume a ban on all new semi-autos, normal capacity magazine, or the transfers of those.
Markets: Drying up the civilian market would obviously cause a lot of current producers to fold their doors, especially the smaller outfits. Unless they could make the change to bolt guns (bound to become better sellers), or get and keep military and police contracts. Then the firearms available to the public would cost more since the volume would be lower (eventually, not counting the current buying frenzy).
Regulations: Paying for all the checks, record keeping, registries, etc. also has costs involved and guess who will pay them; gun owners. If it is anything close to the hoops one has to go through to own a firearm in DC, you’re talking a couple days (or more) of in-person filings at various offices, and hundreds of dollars of fees, on top of the cost of probably mandatory firearms training.
Overall effect: Shrink the market; make legally owning firearms prohibitively expensive for most Americans. Key work there is legally – the bad guys won’t be paying any of those fees, and won’t be limited to whatever the nanny-state allows.
Some Republicans may roll over: See info from the Doc Thompson Show.
Nutnfancy explains a Second Amendment issue: Many for gun control think those who favor owning firearms as a check on the government are delusional since modern militaries are so powerful. Nutn explains that semi-auto rifles can get one a crew-served weapon, etc.
