MasterPiece Arms Defender Pistol now California compliant.

MasterPiece Arms (MPA) Defender series of Pistols has been tested…

MasterPiece Arms (MPA) Defender series of Pistols has been tested and has met with all of the State of California’s requirements on the sale and ownership of a single-shot pistol. The California Edition Defender pistols include models for the top and side-cocking, 9mm and .45 ACP. MPA redesigned the Defender CA pistols in their state-of-the-art manufacturing facility in Carrollton, Georgia to meet California pistol requirements for the weapon to be considered a single shot pistol. This includes “single-shot only” capability, a permanent muzzle-break and zero round capacity “dummy” magazine. MPA’s magazine lock design renders the “dummy” magazine “non-detachable” under California law.

The California compliant Defender pistols meet all size and length requirements, as well. All pistols include a MasterPiece Arms case for the pistol and accessories and a lifetime warranty on every one of MasterPiece Arms Defender pistols.

    For a pistol to be sold in CA it has to be on a roster of “not unsafe” handguns as tested and certified by the DOJ. This type of single shot pistol meets a roster exemption, allowing it to be imported here. Once the pistol is sold, there is no law preventing you from removing the zero round magazine and using any other legal magazine.

    Living here in Idaho I’m confused. This is now a single shot machine pistol?
