BudsGunShop.com - Are the Bond derringers Mass compliant ?

No not MA compliant, buds does have a filter to show only MA compliant handguns, all of these are MA compliant.

Mark, no Sir. They would have to be included on the MA to be MA compliant : mass.gov/doc/approved-firearms-roster-7/download

Mark, unfortunately it is not MA compliant. It is not on the MA approved firearm roster, which you can see here >>>>> mass.gov/doc/approved-firearms-roster-7/download

NO, Bond Arms derringers are not listed in Mass compliant section of Buds handgun. Thus, Buds will not sell it to customers from Mass. I hope this helps
