I prefer the lighter, faster 9mm rounds. They are my personal choice for carry. Penetration is adequate and expansion is good. I would like to always have a .357 magnum or a .45 acp, but I compromise for ease of concealment.
I have not tried the Speer. I carry Hornady Critical Defense 115 gr, Federal Hydra-Shok in 124 gr and I have some Federal Hydra-Shok LEO in 115 gr +P+. I also carry RBCD frangible 9 mm.
Will have to look into the Gold Dots, like the idea of bonded.
