The technology behind this carbine is 1860s. The design is 1870s. This one is in .44Mag, but they are also available in .45Colt — again, 1870s technology that can work even with black powder and cast lead bullets. As we have seen with the recent drive to make more and more people outright ineligible for legal gun ownership, the anti freedom forces have dropped the pretense of being concerned with modern weapons alone.
States like New Jersey regulate air guns as firearms without as much as an exemption for very low power models. Anything not under their direct control that can throw an aimed projectile is anathema to them. Air guns and .22s are useful for training and, in a pinch, they are better than nothing for defense.
So the current push is to prohibit “crazy” people from having guns, then to expand the definition of crazy as extensively as they can. Then they exempt themselves and their political supporters from the onerous laws and restrictions. The classic 1930s recipe used by Nazis and Communists both. It’s all about power over others, and that power is easier to maintain and to wield with impunity when the commoners are unprotected and vulnerable.
This would also give our rulers every excuse to raid anyone they dislike. One important difference between the war on privacy (aka “war on drugs”) and the war on personal guns: it’s harder to use a pot plant to defend yourself than a rifle. And if you think that pot growers are enthusiastic about protecting their patches, just wait what gun owners will do to protect their families from raids and to avenge raids already conducted.
