A federal judge on Wednesday refused to stop Colorado from enforcing a 2025 statute that bars rapid-fire devices and confines semiautomatic firearm purchases to people who finish a required safety course. Senior U.S. District Judge William Martinez stated in a 35-page ruling that the challengers had not shown a substantial likelihood of winning their Second Amendment claim, so they also had not shown irreparable harm, and that the remaining injunction factors favored the state. Lawmakers enacted SB25-3, the Act Concerning the Prohibition of Certain Semiautomatic Firearms and Rapid-Fire Devices, which took effect in August; a first violation is a class 2 misdemeanor and later ones are class 6 felonies. Purchasers must complete hunter education that includes a four-hour safety course or a 12-hour class over two days taught by a sheriff-verified instructor, with exam results entered in a statewide database, after which a sheriff generally issues an eligibility card unless prior conduct creates a reasonable belief the applicant would endanger self or others.
