This refers to the practice of using specialized handgun cartridges loaded with small lead shot, typically #9 shot, fired from a Glock pistol. These cartridges are designed for short-range pest control, particularly against snakes and other small varmints. A typical scenario might involve a homeowner using such a load to dispatch a venomous snake that has encroached on their property.
The primary advantage of this approach lies in its accessible platform the widespread availability and familiarity of Glock pistols. Using a firearm already owned for self-defense offers a convenient and potentially cost-effective solution for close-range pest management, negating the need for a dedicated shotgun or other specialized firearm. Historically, this practice has emerged as a response to the need for a manageable and readily available method of dealing with potentially dangerous pests in close proximity to homes and livestock.
