Beretta has come up with a better solution. Beretta realized that pistol owners might want to upgrade their frames, or have multiple frames for the same serialized handgun — one frame could have a short grip and while another has a full-sized grip. With its new Beretta BU-9 Nano subcompact 9mm pistol (to be released in October), the serial number is stamped on a separate, removable internal chassis. The polymer frame bears no serial number. As a result, Nano pistol owners can purchase additional frames without legal restrictions. Acquiring a new Nano frame would be just like buying a new recoil spring or other accessory.

We hope other manufacturers follow Beretta’s lead. Removing the serial number from a handgun’s external polymer shell allows aftermarket companies to develop a variety of frames with different features. Aftermarket frames could even be custom-molded to fit the owner’s hand. Additionally, the gun manufacturer could package multiple frames with one chassis for the original sale. That would appeal to folks who want a stubby grip for carry and a full-size grip for gun games.

Along with its novel serialized “modular chassis”, the new Nano has some other interesting features, including a push-button “striker de-activator”. This allows the gun to be disassembled without pulling the trigger. Also both front and rear sights are secured with set screws. This allows a user to easily adjust (or change out) the sights without expensive tools. These features are explained in the video below.
