If you live in the US and can legally obtain firearms you definitely should. Not because you will be fighting against the US gov or some other country's army, but because the "locals" might get a little crazy if the gov ever has to shut off the "free stuff". Imagine the "protests" you will see when that day comes. As you know, "protest" is key word for looting, pillaging, killing, etc, because we are not talking about the olden days protests, but instead like what you have seen in recent years (think Ferguson, etc). Besides that, violent crime is high in many urban areas here and you can't count on a cop saving you if you get attacked- when seconds count the police are only minutes away as they say.
I recommend Glock for handguns for home protection and carry if you don't mind carrying a larger gun (highly reliable and virtually indestructible), although my concealed carry gun is a Smith and Wesson 642 (and 442) because they are light, have no external hammer to catch on pocket and don't print in my front pocket in a pocket holster- although I don't really care for the .38 special caliber but I use Speer Gold dot 38 plus p rounds so the pros outweigh the cons.
I am glad many states moved to allow concealed carry in recent years. I am more glad millions have obtained their licenses as the law allows. I doubt you will get many positive comments here regarding guns though Copperhead since there is a high number of folks from anti-gun ownership countries. These types have no clue what it is like to live in the US and to daily face threats from violent criminals that they will never see in their countries like we have here and in such numbers.
PS I would sell my silver before my guns if I ever got that desperate for cash. I don't think we will see any real attempt to remove the 2nd amendment, at least not for a while. I guess if the US public schools and universities can keep churning out programmed progressive libs that are more interested in trying to pass laws that let men who think they are women use the ladies' bathroom, etc, than what is happening to the rest of the country, we may be doomed in the future. Here is a vid that shows what our future leaders are to be made of possibly.

Just my opinion.
