That type of bill has been introduced by liberals from either Lexington or Louisville every year going back at least 10 years. The bill never goes anywhere because there is no real support for it. However, the legislators are changing and becoming more liberal.
Meeks has one that would eliminate home built guns.

What I want to see put in place are protection bills, ie put in protections for gun owners now while the votes come easy. Sure it won't be a permanent protection but those protections would exist until the liberals take both majorities. For example a prohibition on any entity at any level in the state from passing an ammo tax. We don't have to worry about an ammo tax now but lets put it in writing that one shouldn't exist, creating another hurdle to prevent/delay it in the future. Lexington likes to add extra fees, permits, and inspections for gun related businesses. It's time to get limits put into the state law so that if a hard core liberal took over Lexington they couldn't raise all the fees and permits to the point of running the businesses out of town.
