San Diego County jumped into California’s sprawling ghost gun fight this week, suing a 3-D printing filament manufacturer it says hocks material for homespun firearms in violation of state law.

Working with the Giffords Law Center, the county counsel sued manufacturer Polymaker, alleging the company made a “strategic business choice” to market and sell 3-D printer filament to Californians for the express purpose of building illegal weapons. The polymer filament is sold in spools that feed into 3-D printers, allowing the devices to form designs created by their owners.

Americans can order guns to their doors, but the 3d printers are the issues you choose to tackle...

No, they can't. Guns can only be legally shipped to a federally licensed gun dealer. The dealer cannot transfer it to the buyer without the mandated background check.

The gun laws are already fucked up enough. You don't have to make shit up.

You can have long guns purchased through the Civilian Marksmanship Program shipped directly to your door. Those are a drop in the bucket compared to most firearm purchases in the US, though.

False.

Residents of CA, CT, IL, NJ, NY, OR and WA must have the rifles shipped to an FFL dealer. You must provide a copy of the dealer’s license with your order form. NJ and IL Residents must also provide their FOID card. WA Residents must also provide the I-1639 training certificate.

CMP can't do that in states like California or any of the other states with decent gun laws.

I’ve only been threatened with a gun by the government and I bet that is the case for the vast majority of us.

But you want them to regulate it.

Reading comprehension of a dog.

Talking about regulation (and support for common sense gun laws that would also limit cops) ≠ support for all regulation. You and the people who upvoted you need to retake whatever class you learned English through.

Can order black powder revolvers to your door, and can buy replacement parts that allow them to fire cowboy cartridges, which are just low FPS lead rounds, like 800fps. They'll kill a fella, but don't have quite the same force as modern rounds. They also burn a lower grade powder and are a bit more smokey.

Actually, those conversion cylinders are perfectly happy with modern smokeless powders suitable for their caliber. Though it's more about velocities than pressure. I can load any smokeless .45 Colt for my cylinder that is listed for the standard pressures, (about 11,000psi). But it is highly recommended to keep your velocities no more than 850fps, (the original velocity for the Colt SAA). Frame stretching is the issue. Those cap and ball revolvers are made from a bit softer metal than modern revolvers. Remington's are stronger than the open top Colts.

Trump is trying to pass that law right now, a bit of hyperbole in my statement, but it reinforces my point

This also didn't solve anything, if you look at the statistics.
