Mas Auob (?) in an article stated that a .380 Glaser Safety Slug hit a robber in a liquor store in the shoulder. The responding officer asked "where is the shotgun??) Apparently the Glaser Slug had quite an impact.
I have Glaser Safety Slugs in every Cal I have. And carried them when I worked Armored Cars in San Diego CAL. they were flat nose and susposdily filled with Teflon. I have shot them through metal plates in front of water jugs and they went through the metal plate and ruptured the jug. Very Scientific I know. But what can one do? As far as a civilian on bad guy, at close range, I believe they would preform as advertised.
