I have been using Speer Gold Dot +P ammo since 1986. I had just started as an undercover law enforcement officer in Atlanta GA. I had always had a keen interest in terminal ballistics so I had been testing different ammo into clay for my personal information. The first shot with the Speer 9mm +P, I thought to myself this is going to be hard to beat! As it ended up nothing beat it and nothing has beat it to date. I am now retired and still carry Speer 9mm +P in my personal carry sidearm and in my 9mm Subgun.
