Federal judge blocks Colorado gun law raising minimum age for purchases to 21

A federal judge temporarily blocked a Colorado law raising the minimum age to purchase firearms to 21, just hours before it was set to take effect.
The judge said the gun rights group that challenged the law demonstrated a likelihood of success in proving it infringes on 18- to 20-year-olds' Second Amendment rights.
The law was signed by Colorado's governor in response to mass shootings, with proponents arguing it protects youth while opponents raise concerns about rights and profits.
The judge referenced a recent Supreme Court ruling expanding gun rights in deciding to halt enforcement of the law.
The preliminary injunction prevents the law from taking effect while a lawsuit challenging its constitutionality proceeds.
