Forgot about Glaser, it's been so long since I've heard the name. IIRC it's primary selling point was greatly reducing ricochets but also alluded its massive (but shallow) wound made it a good defense round.

I think the maker was hoping it'd catch on with the police market but it never really took off. With the ever present concern of civil liability for stray or over-penetrating shots, I can see the where they thought they had the LE market. I never bought any as I could only envision very limited circumstances for its use, i.e. dispatching an injured animal on a hard surface.
