I've been very happy with my old original Shield. This Shield Plus is the first handgun in this size that's come along since that I may actually buy as a replacement. A few more rounds, a flat trigger, the 2.0 grip texture and M&P reliability which I personally regard as equal to Glock at the top of the heap. Plus I can get one without a manual safety which wasn't an option when I got my Shield. I like the safety on the Shield as far as they go, it's not obtrusive but still easy to operate and very tactile. But I've gotten to where I prefer no manual safety.
BTW, the 10 lb trigger is just in certain restricted states.
