I cannot create an article about the "Roebuck Quad Lock 9mm Cpx 1" because this appears to be a fictional or non-existent firearm. There is no publicly available information about a firearm with that specific name and designation. My knowledge base is limited to real-world information, and I cannot generate content about products that do not exist.
If you have misspelled the name, or are referring to a specific firearm manufacturer and model that has a similar designation, please provide more details so I can assist you in finding relevant information. I can then provide you with information on firearm safety, responsible gun ownership, or related topics based on your corrected request.
