I have always been a fan of Glazer ammo. I haven't kept up with the exact stats of this ammo, so some of my statements may be off a little. Use Google to get exact info.
Back in the mid 90s this ammo came to my attention. I think the .380 round carries 300 #9 shot bbs. The copper jacket is highly serrated and a dab of blue wax holds the bbs in place. The article I read said, at that time, there were 356 people shot and 356 people won't be robbing any more US tax payers. Even though many bandits made it to the hospital the doctors were not able to sew up all the wholes in there intestines. This round upon impact, due to serration expands all its energy in the body cavity, it literally explodes upon inpac, won't over penatrat and go through interior walls of a house and injure people in the next room or exit a house. My 2 cents is its the perfect defense round. It does not have to be loaded hot to do its dammage, won't exit 1 body cavity and injured a second person, doesn't over penatrat going from room to other rooms, doesn't have excessive muzzle flash. What more could a home owner and care giver want for defending his family. The proper name is Glazer Safty Ammunition.
