Master New Mexico Gun Laws & Firearms Safety 2026 – Lock, Load, and Be Ready!

In the state of New Mexico, an individual must be 21 years old to legally purchase a handgun from a licensed dealer. This is because the minimum age to purchase a handgun is determined by state law, and in this case, New Mexico has set the age at 21 years old. Options A, C, and D are incorrect because they do not meet the minimum age requirement set by New Mexico for purchasing a handgun. Option A (18 years old) is the minimum age requirement for purchasing a long gun in New Mexico, but not for a handgun. Option C (16 years old) and Option D (25 years old) do not meet the legal age requirement for handgun purchases in New Mexico. Therefore, Option B (21 years old) is the correct answer.
