The Glaser Safety Slug® was designed in 1974 in response to the possibility of having to use a handgun on an airplane by the Sky Marshals. The concerns at that time were over penetration on soft tissue and ricochets on hard surfaces and possible excess penetration. In 2002, we purchased the company, because we knew that Safety Slug would be a perfect compliment to the COR®BONfamily of products and a great home defense round. With a bit of engineering enhancement, today, Glaser® offers this excellent performing self defense round for civilian use. It’s the perfect round for apartment complexes, and close quarter security areas such as; courthouses, hospitals, amusement parks.
