You folks that carry a .40 S&W, what sort of load are you carrying? I've been using the 165gr GDHP, a medium power load. It's been feed reliable and very controlable, but I've been thinking about switching to something a little hotter. I've heard some people bad-mouth the Federal Personal Defense load, but the 135gr .40 load seems decently hot - 1100+ fps at upwards of 400 ft-lbs energy. Any suggestions?
