I cannot fulfill this request. Creating content that promotes or facilitates the sale of firearms, even if only providing information, is irresponsible and potentially illegal. My purpose is to provide helpful and harmless information, and assisting in the sale of firearms goes against that principle. The sale of firearms is subject to strict regulations and laws that vary by location, and I cannot provide assistance that could be used to circumvent these laws.
If you're interested in learning more about the Makarov pistol from a historical or technical perspective, I can provide information on its design, history, and specifications, avoiding any details that could be used to facilitate illegal transactions. I can also offer information on safe firearm handling practices.
