Nobody can give you a definitive answer, and that is the honest state of the law. A frame transfer in Massachusetts rests on a reading of the 2024 firearms law that no state agency has put in writing, and experienced Massachusetts firearms attorneys disagree about it. Dealers are split too. Some handle frame transfers; others refuse outright.
What a Frame Transfer Is
A Massachusetts dealer can only sell you a handgun listed on the state’s approved handgun roster. The Attorney General’s handgun sales regulations apply on top of that, and a pistol can satisfy one and fail the other. Neither system bans ownership. Both restrict what a dealer may hand you across the counter.
A frame transfer works in that gap. Rather than selling a complete pistol, the dealer transfers only the serialized frame, the part the government treats as the firearm. The buyer sources the slide, barrel, and remaining parts separately, then assembles the pistol.
Two features of the rules made this possible. The roster depends on laboratory testing, which means dropping the gun, firing it, and measuring accuracy. None of that can be performed on a bare frame. And the Attorney General’s regulations define a handgun as a weapon that fires a projectile, which a frame does not do.
Why the 2024 law Unsettled Frame Transfers in Massachusetts
The firearms law that took effect in October 2024 rewrote the definition of “firearm“ to include the frame or receiver, finished or unfinished.
That created a puzzle. If a frame is now a firearm, and a dealer may only sell rostered firearms, then arguably no dealer can transfer a frame at all.
The state’s Firearm Control Advisory Board faced the identical problem for rifles and shotguns. In February 2025, its subcommittee sent the Secretary of Public Safety a memo relying on a phrase at the top of the definitions section, which says those definitions apply unless the context clearly requires otherwise. The Legislature expanded the word “firearm,” the memo reasoned, but never adjusted the testing standards, and those tests cannot be run on a rifle, a shotgun, or a frame. The Secretary agreed.
No Comparable Written Decision Exists For Handgun Frames
Gun Owners’ Action League, which holds a seat on that board, reported that the question came up at the April 2025 meeting and was answered yes, with the observation that it probably did not warrant mention in the guidance letters. That is a private organization’s account of a conversation. The state publishes board minutes only through December 2024. There is no letter, no regulation, no court decision.
Other Massachusetts firearms attorneys read it the opposite way. Because frames are now firearms, they argue, frames are subject to the roster like anything else, so only the frame of a handgun already on the roster may be transferred. Under that reading a frame transfer defeats the Attorney General’s regulations but not the roster. At least one well-known Massachusetts dealer follows exactly that policy.
The Serialization Question Almost Nobody Discusses
There is a second unresolved issue, and it carries more risk.
State law prohibits assembling a privately made firearm without first obtaining a serial number from the state, engraving it during assembly, and registering within seven days. A privately made firearm is one assembled by someone who is not a licensed manufacturer. Read literally, that describes a licensed owner building a pistol on a frame bought from a dealer.
The regulation written to implement that section exempts firearms that already carry a serial number, and a dealer-transferred frame arrives with one from the factory. But the statute’s own list of exceptions does not contain that exemption. A regulation cannot narrow a criminal prohibition, and no Massachusetts court has addressed the mismatch.
What to Keep in Mind Before You Buy
An LTC is required. A pistol frame is a firearm under current Massachusetts law, so licensing rules apply to the frame itself, not just the finished pistol.
Registration attaches twice. The frame transfer must be reported through the state portal, and assembling the completed pistol triggers a separate registration requirement.
Assault-style firearm restrictions still apply. Nothing about a frame transfer creates an exception for a receiver that is the same as or interchangeable with a restricted model.
The November ballot matters. Question 9 asks voters whether to keep the 2024 firearms law. If it is repealed, the provisions treating frames as firearms disappear, and this analysis changes substantially.
