I can't believe the difference in trigger between my FS40 and my 9 Shield. The FS40 is gritty (still haven't polished the transfer bar) and heavy, Shield is smooth and light. FS40 is about 3 months old (looks like it has the newer sear) and I just bought the Shield. The gritty feel of the 40 is no big deal, it's all in the take-up, but the weight of the break is much more on the 40. I've read S&W did some redesign when they brought out the Shield but I would have thought they would carry it over to the full size guns. Just gun to gun variation or has anyone else noticed ?
