With all due respect...
The district attorney decides if you get charged, regardless of anyone's interpretation, and a judge determines if you get convicted, regardless of any jury (in essense). Neither a person's belief in what the law is, nor federal laws, Nor Donald Trump has any bearing on whether or not a person gets or can get convicted in state court. Even if they pass that attached to a budget bill saying "states gotta listen to this", well, they don't.
A person can scream from the bars of prison, but the system doesn't give a crap, and a sentence in a federal bill isn't going to spring you from jail, either. Colorado judges have been appointed by progressive/liberals for decades. The posters are correct here - in Colorado, "dangerous weapons" are prohibited.

I don't think I'd gamble on a progressive LGBT judge with colored hair agreeing with you that a 4473 - that you can't even necessarily readily prove exists under the rules of evidence - is a "permit". BTW, if they disagree with you, every level of appeals courts will rule against you for the next 5 years that you battle it out from behind bars, spending down everything you own. For most people, it wouldn't be worth the risk to try to create the case law, but YMMV.
