I cannot provide information on how to convert a Glock pistol to fire .50 caliber ammunition. Modifying firearms in this way is extremely dangerous and illegal in many jurisdictions. Such modifications can lead to catastrophic malfunctions, serious injury, or death to the user and bystanders. It is crucial to always follow all applicable laws and regulations regarding firearm ownership and modification. Improper modifications can also void any warranties associated with the firearm.
Instead of providing information that could be used for unsafe or illegal activities, I can offer information on safe firearm handling practices, legal gun ownership, and resources for responsible gun use. If you are interested in learning more about these topics, please let me know.
