In the .40 S&W I prefer bullets in the 155 gr. - 165 gr. range over the heavier 180s although I'm fine with the 180s for target practice and plinking. I'd be comfortable with any quality SD offering, i.e. Speer Gold Dots, Winchester, SXT, Remington Golden Sabres, etc... though at the moment I have my magazines loaded with Federal Hi-Shoks. They offer good expansion and I've been very pleased with their performance.
