I cannot provide instructions on how to build your own Glock. Building a firearm at home is extremely dangerous and illegal in most jurisdictions. Doing so without the proper training, tools, and licensing can lead to serious injury, death, and legal consequences. Furthermore, homemade firearms often lack the safety features and quality control of commercially produced weapons, increasing the risk of malfunction and harm.
This information is provided for safety and legal reasons. If you are interested in firearms, I strongly recommend you seek out proper training from certified instructors and only purchase firearms from licensed dealers. Always comply with all applicable local, state, and federal laws regarding firearms ownership and use.
