MGL Chapter 140, Section 123:
Dealer Licensing Requirements

Massachusetts General Laws Chapter 140, Section 123^[1] establishes all operational compliance conditions governing how licensed firearms dealers must conduct business under their Section 122 licenses.

Key Requirements

Chapter 135 of the Acts of 2024^[2] completely restructured the section from numbered conditions to lettered subsections (a) through (p). Core requirements include:

• Premises: Non-residential business premises required, with license displayed and no firearm displayed in an outer window or any other place where it can be readily seen from outside the premises
• Safety postings: Conspicuous posting of safe transportation and storage information (developed by DCJIS) and suicide prevention information (developed by EOPSS with DPH)
• Pre-transfer verification: Verification of license, card, permit, or exemption status with identity confirmation before any transfer
• Expired credentials: Expanded procedures including issuing a receipt valid for 90 days (the earlier text made the receipt valid only for the date of issuance), confiscating the credential, forwarding it to the licensing authority, and notifying the holder of their duty to surrender firearms under Section 129D
• Record-keeping: An on-site or electronic transaction record, open to police inspection at all times
• Loss and theft: Reporting via the Section 121B registration system
• Gun shows: Sales and transfers permitted at a regular meeting of an incorporated collectors club or at a gun show open to the general public, if the licensee complies with all other Section 123 provisions and with federal and state law
• Remote orders: A licensee may not fill a mail, facsimile, telephone, internet, or other telecommunication order unless the transaction includes in-person presentation of the required license, card, permit, or documentation before any sale, delivery, or transfer (transactions between federally licensed dealers exempt)
• Delivery: All firearms and ammunition delivered unloaded

Consumer Protection Testing

Section 123(o) bars a licensee from transferring certain firearms except to a business entity that is primarily a firearm wholesaler. The covered firearms are those with a frame, barrel, cylinder, slide, or breechblock made of metal with a melting point under 900 degrees Fahrenheit, an ultimate tensile strength under 55,000 psi, or a powdered metal density under 7.5 g/cm³ (unless three samples of the make and model pass a 600-round firing test), those prone to accidental discharge (five samples dropped from 1 meter in 6 positions must not discharge), those prone to firing more than once per trigger pull or to explosion during firing, and those with a barrel under 3 inches unless the licensee gives the buyer a written accuracy disclosure. These conditions were added to the former Section 123 as Clauses Eighteenth to Twenty-first in 1998 and now appear in subsection (o).

Penalties

New under Chapter 135: any licensee, employee, or agent who violates Section 123 faces a fine of not less than $1,000 nor more than $10,000, imprisonment for not less than 1 year nor more than 10 years, or both. Former Section 125, in effect until January 25, 2026, separately allowed the licensing officials to declare a license forfeited or suspend it after notice for violating a license condition or a provision of the chapter.

Inspection

The local licensing authority must enter premises at least once per calendar year. Under Chapter 135, the Department of State Police may assume the local authority's licensing responsibilities for the calendar year upon written request at least 6 months in advance of any required inspection, and may become the inspecting authority if the local authority fails to inspect. EOPSS promulgates rules for inspection standards.

Related Provisions

Section 122 governs license issuance. Section 121B establishes the electronic registration system used for recordkeeping. Current Section 125 covers dealer training. Section 129D governs the surrender of firearms upon license revocation.

Referendum Status

Subject to the November 2026 referendum. A related delayed amendment, Chapter 135, Section 38, which replaced Section 125 on licensing-authority training, took effect January 25, 2026 under Section 159 of Chapter 135 as amended by Chapter 206 of the Acts of 2024, Section 51.
