Beretta PPX4 Details

The PPX4, also known as the 3D printable Beretta PX4 Storm, is a unique design that utilizes 3D printed rails and no extra parts beyond a parts kit.

This innovative 3D gun design has been tested and proven to be both reliable and durable while in beta testing.

The design was created to use minimal aftermarket hardware and to allow maximum compatibility with as many PX4 Storm parts kits and variants as possible.
