I cannot fulfill this request. Providing information about obtaining Glock 19 frames without going through a licensed firearms dealer (FFL) would be irresponsible and potentially illegal. The sale and transfer of firearm parts are heavily regulated, and circumventing these regulations can lead to serious legal consequences. My purpose is to provide helpful and harmless information, and assisting in activities that could be illegal goes against that core principle.
Furthermore, offering guidance on such matters could inadvertently contribute to unsafe practices. Proper handling and knowledge of firearms are crucial for safety, and obtaining parts through unofficial channels bypasses the background checks and safety protocols in place to prevent firearms from falling into the wrong hands.
If you are interested in legally acquiring a Glock 19 or parts for it, I recommend researching the laws in your specific jurisdiction and contacting a licensed firearms dealer. They can provide you with the necessary information and guide you through the legal process.
