New Mexico Senate Bill 17

New Mexico Senate Bill 17, titled the “Stop Illegal Gun Trade and Extremely Dangerous Weapons Act,” is a comprehensive measure introduced in the 2026 legislative session to address firearm trafficking, enhance oversight of licensed gun dealers, and restrict certain weapons and accessories. The bill targets issues like straw purchases—where individuals buy firearms legally on behalf of prohibited persons—and aims to reduce guns used in crimes that originate from local retailers.

A major focus is on regulating firearm dealers. It requires dealers to implement enhanced security measures to prevent theft and loss, including monitored alarm systems, hardened doors and windows, video surveillance at key points (with recordings retained for at least two years), and other reasonable safeguards. The Department of Public Safety must promulgate rules for these by specified dates, with potential exemptions or tailoring for smaller or home-based operations.

The bill sets employment standards for dealers: employees who handle, sell, or deliver firearms must be at least 21 years old, pass background checks (using systems like NICS where federally allowed), and complete mandatory training. Training, developed by the state, covers topics such as recognizing and preventing straw purchases, firearm laws, theft prevention, gun safety, and suicide awareness. Dealers must complete this training themselves and provide it to new hires within 30 days and to all employees annually.

Dealers face new recordkeeping and reporting obligations. They must maintain thorough records of transactions and inventory, report crime gun traces, multiple sales, thefts, and losses promptly (with tight deadlines like 24 hours in some cases), and cooperate with inspections. The bill also requires posting prominent notices in stores informing customers about safe storage, background check rules, and the illegality of straw purchases.

The most controversial provision prohibits the sale or transfer of “extremely dangerous weapons” to unlicensed individuals starting July 1, 2026. This includes .50 caliber rifles and cartridges, detachable magazines holding more than 10 rounds, and certain gas-operated semi-automatic firearms (such as many common rifles and shotguns capable of accepting detachable magazines). Exceptions apply to antiques and some other categories.

Violations carry penalties, ranging from civil fines to misdemeanor or felony charges depending on the offense, such as falsifying reports or failing to comply with security/training rules.

Proponents argue the bill holds dealers to standards similar to those for alcohol or cannabis sellers, curbs trafficking based on reports showing many crime guns trace to nearby retailers, and removes military-style weapons from circulation to improve public safety. Critics contend it imposes burdensome, costly requirements on small businesses, creates privacy concerns through expanded recordkeeping, and unconstitutionally bans commonly used firearms for lawful purposes like hunting, sport shooting, and self-defense.

As of mid-February 2026, the bill passed the Senate but faced ongoing debate, amendments, and committee action in the House during the session’s final days.
