Massachusetts has one of the most restrictive handgun purchasing systems in the country. A handgun must clear three independent regulatory layers before a dealer can sell it: the EOPSS Approved Firearms Roster (501 CMR 7.00[1]), the Attorney General's consumer protection regulations (940 CMR 16.00[2]), and any active AG enforcement notices. Many popular handguns fail one or more of these layers. Glock pistols, for example, appear on the roster but are blocked by 940 CMR 16.00 because their extractor indicator was determined not to be an effective loaded chamber indicator.
Frame transfers are a legal method that LTC holders use to obtain these otherwise dealer-restricted handguns. This guide explains how the process works, why it is legal, and what you need to know before pursuing one.
What Is a Frame Transfer?
A frame transfer is a purchase where a licensed dealer sells you a serialized handgun frame (the lower receiver) as a standalone item, rather than as part of a complete handgun. The remaining components (slide, barrel, recoil spring assembly, and other small parts) are sold separately as non-firearm parts. You take everything home, assemble the complete handgun yourself, and register it through the Massachusetts firearms registration system.
Under federal law (18 U.S.C. § 921(a)(3)[3]), the frame or receiver is the legally regulated component. It has a serial number engraved by the manufacturer, and its sale requires a Form 4473 and NICS background check through a licensed dealer, just like any other firearm. The slide, barrel, springs, and other parts are not firearms under federal law and can be sold without a background check.
Why Frame Transfers Are Legal
The legality of frame transfers rests on a straightforward regulatory distinction: a frame is not a handgun.
940 CMR 16.00 Applies to Handguns, Not Frames
The AG's consumer protection regulations define their scope as applying to "handgun-purveyors" selling "handguns" to Massachusetts consumers[2]. The regulation's testing requirements (loaded chamber indicator, magazine safety disconnect, drop test, trigger pull weight, childproofing) are designed for complete, functional handguns. A bare frame cannot fire, has no trigger pull to measure, no chamber to indicate, and no magazine to disconnect. It is not a handgun under 940 CMR 16.00.
The Approved Firearms Roster Lists Complete Handguns
The EOPSS Approved Firearms Roster under 501 CMR 7.00[1] catalogs specific handgun models by manufacturer, model name, caliber, and barrel length. A frame or receiver is not a complete handgun model and does not appear on (or need to appear on) the roster.
Federal Law Classifies the Frame as a Firearm
Under 18 U.S.C. § 921(a)(3)[3], the frame is a "firearm" for purposes of dealer licensing, background checks, and record-keeping. This means the sale still goes through proper channels: the dealer runs a background check, completes a Form 4473, and the transaction is recorded. There is nothing clandestine about the process.
How It Works Step by Step
- Find a dealer who offers frame transfers. Not all Massachusetts FFLs provide this service. Some dealers, such as Fudd Free Firearms, specialize in frame transfers and parts kit sales, handling the process regularly. Call ahead to confirm availability and pricing for the specific model you want.
- Purchase the frame. The dealer sells you the serialized frame as a firearm. You must present your LTC, complete the ATF Form 4473, and pass the NICS background check. The dealer records the transaction in their bound book. This is a standard firearms purchase from the dealer's perspective.
- Purchase the parts. The remaining components (slide assembly, barrel, recoil spring, pins, and other small parts) are sold to you separately. These are not firearms under federal or state law and do not require a background check. Some dealers sell these as a bundled parts kit alongside the frame; others may direct you to purchase parts independently.
- Assemble the firearm at home. Assembly of common handgun platforms (such as Glocks) typically requires no specialized tools and can be completed in minutes using manufacturer instructions or widely available guides. Ensure the firearm functions safely before loading it.
- Register within 7 days. Under M.G.L. c. 140, Section 128A[4], you must register the completed firearm through the MIRCS Unified Gun Portal at gunportal.mass.gov within 7 days of acquisition. Register using the serial number from the frame, the manufacturer, and the final configuration (caliber, model).
This Is Not a Ghost Gun
Frame transfers are sometimes confused with ghost guns. They are entirely different.
A ghost gun (legally, an "untraceable firearm" under M.G.L. c. 140, Section 121[5]) is a firearm that lacks a serial number. This includes firearms assembled from unserialized parts kits, 3D-printed frames, or so-called "80% lowers." Manufacturing, possessing, selling, or transferring an untraceable firearm is a criminal offense under Sections 121C and 121D, carrying a mandatory minimum sentence of 12 months imprisonment[6].
In a frame transfer, the frame is manufactured by a licensed company, bears a factory-engraved serial number, and is sold through a licensed dealer with a full background check and ATF paperwork. It is fully traceable, fully serialized, and fully legal. The completed firearm is then registered in the state system. There is no overlap with ghost gun prohibitions.
Common Models Obtained Through Frame Transfers
The most common handguns acquired through frame transfers are models that appear on the EOPSS roster but are blocked by 940 CMR 16.00's loaded chamber indicator or magazine disconnect requirements:
- Glock pistols (all models): Blocked since 2004 after AG Reilly determined Glock's extractor indicator was not an effective loaded chamber indicator
- Various striker-fired pistols: Many modern striker-fired designs lack a magazine disconnect safety or an AG-compliant loaded chamber indicator
Handguns that are not on the EOPSS roster at all cannot be sold by dealers even as frames, because the frame itself is still a restricted item in that context. Frame transfers specifically address the gap between the roster (which lists the model) and 940 CMR 16.00 (which blocks the complete handgun sale).
What You Need
- A valid Massachusetts LTC. An FID card is not sufficient for handgun frame purchases.
- A dealer who offers the service. Not every FFL is willing to handle frame transfers. Dealers who do this understand the regulatory framework and can walk you through the process.
- Budget for the premium. Frame transfers typically cost more than buying a complete handgun in a free state. The frame and parts purchased separately often total more than the manufacturer's suggested retail price, and the dealer may charge a service fee. This is the cost of navigating the Massachusetts regulatory system.
Chapter 135 Impact
Chapter 135 of the Acts of 2024[7] expanded the definition of "firearm" in Section 121 to explicitly include frames and receivers, whether finished or unfinished. This means:
- The frame purchase is clearly a firearms transaction subject to all state licensing requirements
- An LTC is required (no ambiguity about whether a frame alone falls under the firearms licensing framework)
- The frame must be registered through the MIRCS system
- Private resale of the completed firearm counts toward the 4-transfer annual cap under Section 128A
Chapter 135 did not amend 940 CMR 16.00, which remains an independent AG regulation under Chapter 93A. The distinction between a frame and a complete handgun under the AG's consumer protection framework is unchanged.
Other Legal Ways to Obtain Restricted Handguns
Frame transfers are not the only path. Massachusetts law provides several other legal avenues for obtaining handguns that dealers cannot sell as complete firearms:
- Private sales: Transfers between LTC holders are not subject to 940 CMR 16.00 or the roster[4]. Both parties must file through the MIRCS portal. The seller is limited to 4 transfers per calendar year. This is why Glocks and other restricted models command a significant premium on the private market in Massachusetts.
- Pre-October 21, 1998 manufactured firearms: Dealers may sell handguns manufactured before this date even if the model does not meet current 940 CMR 16.00 requirements. The regulation applies to handguns sold "on or after" its effective date, and pre-date manufactured firearms are exempt from certain testing requirements.
- Law enforcement trade-ins: Firearms that enter the commercial market through law enforcement agency trade-in programs may be available through dealers, though availability varies.
Granata v. Campbell: The Constitutional Challenge
The entire Massachusetts handgun sales regulatory framework is under active legal challenge. In Granata v. Campbell[8], the Firearms Policy Coalition and individual gun owners argue that the roster and 940 CMR 16.00 violate the Second Amendment under the Supreme Court's Bruen framework. On January 28, 2026, the Trump DOJ filed an amicus brief supporting the plaintiffs[9]. The case is pending before the First Circuit as of March 2026. If the court strikes down the roster or the AG regulations, frame transfers would become unnecessary because dealers could sell complete handguns directly.
Important Considerations
- No court has ruled specifically on frame transfers. The legality rests on the regulatory distinction between a frame and a complete handgun. This distinction is well-established in practice and widely relied upon by dealers and purchasers across the state, but it has not been tested in a Massachusetts appellate court.
- AG enforcement could change. A future Attorney General could attempt to extend 940 CMR 16.00 to cover frame sales. No AG has done so to date.
